Position of the heads on the satellite dish. How to install and configure a satellite dish yourself
At this stage, we need to determine the approximate tilt of the mirror of our satellite dish in a vertical plane.
You can, of course, not calculate this parameter. But, knowing the correct tilt of the satellite dish will save a beginner, if the search for a signal is unsuccessful, from unnecessary assumptions." Is the antenna positioned correctly?? ". For example, if, when setting up, you deflect the antenna mirror quite strongly to the top (or to the bottom). After all, you will already have a visual idea of how it should stand, and in any case, you will return satellite dish mirror to its original state, after which, continuing the search.
Although, of course, this will not get rid of manual settings, but still, it will significantly facilitate the whole process satellite dish settings(while also saving time).
Now let's calculate what slope the offset mirror will have satellite dish.
Satellite dish tilt - tilt angle calculation
Unfortunately, since satellite dish tilt, directly depends on its diameter and shape, in order to calculate this slope, alas... it is necessary to make calculations using special formulas.
I don't want to overload your head with already quite a lot of information. Therefore, here I will suggest three ways:
First way. Don't do any calculations now. When adjusting the vertical position of the antenna, first place it in a vertical position. Then, gradually lower the mirror down (or raise) until a signal from the satellite appears. In principle, this is what all experienced tuners do.
Second way. Emphasize on tilt angle satellite dishes installed nearby, for example, on the same house, or on the balconies and roofs of neighboring buildings.
Third way. To do calculating the tilt angle of a satellite dish To do this, use any computer program.
To make it more clear, to determine the tilt of the antenna, I will use the same program “Satellite Antenna Alignment”.
To do this, launch this program and go to the “ Offset antenna».
Determining the tilt of a satellite dish.
In the satellite selection window, select the one for which the satellite dish will be configured. In this case, I chose the Express AM 22 satellite (Photo 2).
Photo 2. We select the satellite for which the satellite dish will be configured.
Let’s set the dimensions of your antenna mirror in the “Antenna width” and “Antenna height” cells.
We indicate the dimensions of the offset mirror of the satellite dish.
As soon as we enter the dimensions of the antenna, next to the image below, the numerical indicator “Antenna tilt required” will change its value. In my case it was 73.20°.
Satellite dish tilt.
Being at the antenna installation site, based on the fact that we will insert the initial position only visually, it is easier to measure the tilt of the satellite antenna mirror not from the horizontal, as is done in the program, but from the vertical. To put it in more correct words, this will be the Declination angle - that is, the declination angle of the satellite dish mirror.
Satellite dish tilt, or declination angle.
Therefore, to make it more convenient for us, we will do some simple calculations. Since a right angle is 90° degrees:
That is, if we place the satellite dish strictly vertically, then from this position the antenna mirror must be tilted by 16.80 degrees.
In principle, since we will be setting up the satellite dish manually (without any “special tools”), we don’t need such precision. Therefore, take a sheet of paper, draw this angle, and just visually remember its slope.
It turns out... to start setting up a satellite dish for the Express AM 22 satellite, you must initially place it at 16.80° from the vertical position. These meanings naturally apply specifically to my case. Do the calculations for your option, and just remember these two parameters.
No matter what accurate data the Satellite Antenna Alignmen program gives us, we will not be able to take full advantage of this accuracy, since we seem to have nothing to bind to for measurement. After all, we will only have to imagine all the planes needed for counting, and this means that we will measure degrees only in our thoughts, with our internal “degree meter”. But all this is quite enough for our purposes.
And so, we know the coverage area of the chain of satellites visible from the installation site of the satellite dish, and the vertical tilt of the antenna mirror is also known to us. You can basically start preparing satellite equipment. But before that, let's digress a little. I would like to explain some points regarding the vertical adjustment of a satellite dish, which you may also encounter.
Satellite dish tilt - setting
(description of some points related to the vertical alignment of the satellite dish)
In the design of a satellite antenna, the suspension is designed in such a way that the antenna mirror can be equally raised or lowered to the same maximum angle
Satellite dish suspension with equal vertical rotation angle.
But in my practice, I have come across satellite antenna hangers, in the design of which the vertical rotation of the antenna itself was carried out as if tilted to one side. Therefore, with such a design, it is important to assemble it correctly, in accordance with your geographical location, or more precisely, depending on your latitude and the distance of the satellite.
Since I am at a latitude of 63°, the tilt of the satellite dish will be 16.80° from the vertical, and if you mount an antenna with a suspension with a priority tilt in one direction, then you need to place a U-shaped element as in Photo 2 (it shown by red arrow).
At the same time, the angle of travel of the satellite dish mirror just fits into the tilt of “16.80°” (Fig. 1). In this case, it feels as if the antenna itself is looking slightly toward the ground.
If my location were closer to the equator, for example, at 40 degrees north latitude, then in this case, the satellite dish mirror will rise, and the angle of travel should be as in Fig. 2.
In this case, the U-shaped element must be positioned in reverse, as in Photo 3 (here I apologize, I simply turned this photo vertically).
The next point also concerns adjusting the tilt of the satellite dish, or rather, installing the suspension with a slope in one direction, on a vertical support.
When using a satellite dish hanger with a priority slope in one direction, if your location is more distant from the equator, it must be installed on a mount, as in Photo 4 and Photo 5.
Satellite dish, the suspension of which is inclined in one direction
Installed satellite dish.
Since in this case, the satellite dish will have a certain angle of inclination towards the bottom. Therefore, the L-shaped suspension element, at one end of which the converter is fixed, needs to have some free space in the lower part of the structure, allowing this angle of inclination of the antenna to be changed.
To more clearly explain the essence of this problem, which you may also encounter, let’s try to mentally install the already configured satellite dish shown in Photo 4 on a vertical support (Photo 6 and Photo 7).
Homemade vertical satellite tower
Homemade vertical support for installing a satellite dish on a horizontal surface.
Comparing these two images (Photo 8), we will see that the corner of the L-shaped suspension element (Photo 9) rests against the wall of the vertical pipe, and the place where the suspension is fastened does not even reach this pipe.
Naturally, if we nevertheless secure this suspension, pulling it to the pipe itself, the angle of inclination of the satellite dish will change, thereby making further vertical adjustment impossible.
Of course, this option for installing such a suspension, shown on Photo 7, on a vertical support, is quite suitable for those whose antenna mirror will stand almost vertically, or higher. For others, when purchasing a satellite dish, you will have to take into account the problem described above.
Since the satellite antenna itself, as a rule, comes with its own standard suspension, it is better to purchase a support for it, depending on the coordinates of the place where this antenna will be installed.
Based on this, when purchasing a satellite dish and support, it is advisable to already know the tilt angle of the antenna for your area, or rather, the range of this tilt angle.
To find out the tilt range of the satellite dish, let's again use the Satellite Antenna Alignment program. As always, I will explain based on my own example.
Equipment for setting up a satellite dish
The satellite dish is in place, connectors are installed on the cable, and all preliminary settings have been made in the receiver. In order for us to be able to make further adjustments, it is necessary to have free access to the back of the already suspended satellite dish.
To position the satellite dish to the selected satellite, we will need the following equipment for setup:
- 1. A small or portable TV that supports the outputs that are on your receiver.
- 4. Connecting cable (LF or HF) corresponding to the connection between the satellite receiver and TV.
- 5. Wrenches and screwdrivers suitable for fastening the converter and satellite dish mounting.
3. Segment coaxial cable, to connect the receiver to the converter, approximately 1.5...2 meters long, with connector connectors installed at both ends (this cable is used only during setup).
If you don’t have a small portable TV, then, of course, there is no point in buying it specifically for setting up a satellite dish. To avoid unnecessary costs, you can purchase a relatively inexpensive device called "Sat Finder". It was created specifically for setting up satellite dishes at home. At the time of writing this page, the cost of such a device was in the range of 400...700 rubles, which is significantly cheaper compared to the cost of a portable TV. It, of course, has its advantages, and unfortunately, it also has its disadvantages. You can read about what kind of device this is and how to work with it. If this is your first time setting up a satellite dish, then I would still recommend that you use the option with a receiver and a portable TV. I think this will be easier and more reliable for you.
Based on the fact that I will explain the installation and configuration of a satellite dish using my own example, I will use the following equipment and tools:
Digital satellite receiver (in this case, an FTA receiver designed for viewing open channels is suitable for us).
Looking at back panel, you can see that this receiver can be connected to a TV, both at high frequency, from the output of the RF modulator, and at low frequency, through tulip-type audio-video connectors.
Portable TV. In principle, any small TV will do here. The main thing is that it supports the outputs that are present on your satellite receiver.
Looking at the back panel of this TV, you can see that it can also be connected via both a high-frequency input and a low-frequency audio-video input.
If you have a receiver with an HF modulator, then there is no need for low-frequency audio-video connectors, but in this case, the TV must support the UHF radio frequency range (although I do not rule out the possibility that the HF modulators of some receivers, or older model TVs, can only operate in the meter wave range, in the microwave range).
If you have a receiver without an RF modulator, then low-frequency audio-video connectors on the TV itself are required.
A piece of coaxial cable(for connection to the converter), approximately 1.5...2 meters long, and with “connector connectors” installed on this cable at both ends.
LF (low frequency) audio-video cable tulip type, for connecting to a TV via low-frequency output and input.
Radio frequency cable (RF), another name for high frequency cable (HF). For the option of connecting to a TV via a radio frequency antenna input (only if the receiver has an RF modulator).
Due to the presence of an audio-video input on the TV, I will not use this cable.
Wrenches and screwdrivers, for tightening the suspension fasteners and converter fastenings corresponding to your satellite dish kit.
Also, to tighten the connector connector on the satellite converter, you will need an 11-size open-end wrench.
And so, the equipment for setting up the satellite dish and the tool are prepared. Finally, we will need some network extender to bring it to the setting location (to an already installed satellite dish), mains voltage 220 volts. The extension cord must have two sockets for connecting a satellite receiver and a portable TV.
Also, to configure the satellite dish in the horizontal plane, we will need compass.
Connecting equipment for setting up a satellite dish
Now, you can move the tuning equipment and tools to the installation site of the satellite dish. The general diagram of equipment connection for subsequent configuration is shown in Fig. 1.
Rice. 1 General diagram of connecting equipment for setting up a satellite dish.
For convenience, I placed the satellite receiver with TV on a small chair (Photo 1). It is advisable to position the TV itself so that when setting up a satellite dish, you can adjust the direction of its mirror with your hands and look at the TV screen, almost simultaneously.
Photo 1 Connected equipment for setting up a satellite dish.
At the time when the photographs for this page were taken, it was the beginning of winter. Therefore, the temperature outside reached minus 7...10 degrees. In such conditions, it is not advisable to use electronic devices, which are intended to be used at room temperature. But this means that setting up the satellite dish will have to be postponed to a warmer time, which, of course, did not suit me. So I continued with this setup anyway, but... following some rules, and these are:
1. As soon as the equipment is outside, you must immediately supply power to it. This means that you need to not only turn it on, but also take it out of standby mode (take it out of the “standby” mode by pressing the “Power” button, for example, on remote control), that is, bring it into full working mode. This is necessary so that the radio elements of the equipment are heated due to their own thermal radiation. For optimal operation of the device, such heating, of course, is not enough, but this will not allow it to cool down quickly enough.
2. If, in any case, the device was moved back into the heat, before turning it on, you must wait at least 30...40 minutes at room temperature. This also applies to taking it back outside if necessary.
3. It is not advisable to adjust the satellite dish at temperatures below 10..12 degrees.
4. Carry out adjustment work as quickly as possible.
5. If the satellite receiver begins to react poorly to any commands, freezes, or behaves in some other unusual way. Turn it off immediately and bring it into a warm room for 30...40 minutes. And only after that, continue any work with it.
Although, by and large, I would certainly not recommend operating the equipment in such extreme conditions for it. In any case, you will do this at your own responsibility, that is, at your own peril and risk.
When installing satellite equipment in the cold season, it is strongly recommended: all setup of electronic equipment, which can be carried out without being near the satellite antenna structure (for example, pre-setting receiver), carry out it in a warm room, and only after that transfer it to the very place where the satellite dish is installed and configured.
As for the satellite converter itself, it was initially designed by the manufacturer to operate in both normal and low temperature conditions (but I do not exclude that there are models of converters designed to operate in hot countries). The only thing I want to warn you is that if the satellite converter was moved back into the heat, before putting it back into the cold, it is also advisable to wait at least 30...40 minutes....
Now, let's connect the setup coaxial cable, with the connectors installed on it, to the receiver and converter (Photo 2 and Photo 3). Position it so that, if possible, it does not interfere with various manipulations with the satellite dish. When screwing the connector, do it only by hand, since this cable only the adjustment one, then, when you connect the permanent one, tighten the connector with a key (usually an 11 key), but do not overdo it, although it is metal, it is quite fragile.

Connecting a satellite receiver to a TV
Connect the satellite receiver and portable TV (Photo 4). If your TV does not have a low-frequency input, then connect via. But as I already mentioned, for this the receiver must have an RF modulator. Also, in this case, you need to configure your TV to the radio signal coming from the receiver. The principle of setting up the TV itself will be the same as when receiving broadcast programs, the only difference is that instead of terrestrial antenna You will connect the RF cable coming from the satellite receiver.

Below on Photo 5, it is indicated which main connectors may be needed for connection.
Photo 5. Connectors for connecting a satellite dish and TV.
Connect the power plugs of the TV and satellite receiver to the extension cord, and also turn on both devices in full-on mode. If they are connected via an audio-video cable, then switch the TV to receive a video signal (A/V mode); if via an RF modulator, tune your portable TV to the modulator frequency (it is better to do this in advance, in a warm room). In general, ensure that the TV screen displays a stable image transmitted from the satellite receiver.
Setting up a satellite dish for a satellite
Press the button on the receiver Menu", and go to the submenu for editing transponders. Select the satellite of interest, and just in case, check the parameters of the desired transponder(s), which we entered earlier.
Also, if desired, here you can immediately edit the name of this satellite. It should be noted that usually in names you can enter only a certain number of letters, so if the word does not fit, you have to shorten it. I usually try to write the name of the satellite and its position in degrees. Since the number of letters is limited, I abbreviated the satellite “Express AM 22” 53°E as “Exp 22-53”. In principle, the function of renaming satellites is made only for convenience, and there is no special need for it (that is, the name of the satellite does not affect any important parameter). But, if in the future you plan to install a motor on a satellite dish, knowing the name and position of the satellite, it will be easier to navigate when choosing television and radio channels.
Your transponder editing menu may differ significantly from the option I propose, but the basic principle will remain unchanged.
Now let's take a look at the transponder editing menu in more detail, using receiver No. 1 as an example. Such a menu will be our main tool in subsequent setting up a satellite dish for a satellite(Photo 1).
On previous pages, to reduce page download time, I had to crop all the “menu” images, showing only those necessary on this moment, plots. Now, let's look at it in full. In the image, I have highlighted two areas needed for subsequent setup of the satellite dish.
Photo 1. Menu for editing satellite transponders and signal indicator.
In the first section, there are parameters of one of the transponders of the selected satellite. Namely: frequency, symbol rate, and type of polarization. If necessary, we can adjust these parameters.
In the second section, an indicator of signal level and quality is displayed. This indicator, as a rule, has two indicators, calculated as a percentage (%). One indicates its level, may also be designated as - Strength, Level, L, etc. Other, displays quality of this signal may also be designated as - Quality, Q, etc. Based on this indicator of signal level and quality, we will “catch” the satellite we need.
Each satellite receiver, of course, has its own original interface displaying appearance such an indicator. But, in their principle, they are very similar. To make it easier for you to understand how this indicator will look in your receiver, let's look at three of their options.
In receiver No. 1, the satellite signal indicator appears only when there is a signal at the receiver input that matches the transponder parameters, as evidenced by yellow stripes (Photo 2 and Photo 3). That is, it seems to have two states: there is no signal, or its presence, which is usually displayed as a percentage.
Receiver No. 2 has three satellite signal indicator states. The first state (Photo 4) shows the absence of a signal. The second (Photo 5) shows that this signal is there, but the parameters do not correspond to the selected transponder (possibly satellite antenna already configured, but to a different satellite), in this state, the signal strength indicator turns red.
Well, the third state of the indicator satellite signal(Photo 6), shows the presence of this signal, while changing the length and color of the stripes of the indicator itself.
Photo 6 There is a signal.
The third type of indicator of the presence of a signal from a satellite, I took, at that time, from the well-known satellite receiver "DRE 4000" (or DRE 5000). Such a receiver allows you to view the program package of the Russian project, Tricolor-TV, which is broadcast in DRE Crypt encoding. With this satellite receiver, instead of stripes (as in previous versions), the signal is displayed in the form of dots (Photo 7 and Photo 8).
What will it be more quantity points of such an indicator, and accordingly the percentage value, the better the signal characteristics from a given satellite (from a given transponder of this satellite) will be.
Now, I hope you can figure out your indicator without any problems.
And so, the current transponder has been entered, you can move on to the mechanical part of setting up the satellite dish. In principle, judging by this, this is precisely why this entire section was created.
Satellite tuning
At this stage, let's remember what we did when we determined the horizontal direction to the selected satellite, and repeat these steps, but apply this to the satellite dish setup itself. That is, at this stage, we will first align the mirror of our satellite dish in a given direction (in the direction of the selected satellite).
Preliminary horizontal adjustment of the satellite dish
Taking the compass in hand, from the installation site of the satellite dish, we will determine again, based on the azimuth, the direction to the selected satellite (Fig. 1).
Rice. 1. Determining the azimuth direction to the satellite.
Let's set the compass sight in accordance with the azimuth of the selected satellite. Looking through this sight, we will find a landmark on the surface of the earth, which is located in the same direction as the satellite itself.
That is, the direction of the mirror plane of the satellite antenna of the landmark and the satellite will be on the same line.
Selecting a landmark- as a landmark, you can take a tree located on the ground, an electric pole, a house window, and so on... This landmark will be for us, like a beacon, in the direction of which we will initially align the plane of the satellite dish mirror along the horizon (Fig. .2).
Rice. 2. Aligning a satellite dish to a satellite using a landmark.
The presence of a landmark will make it much easier for you to search for a signal from a satellite, without allowing us to move the satellite antenna mirror in the wrong direction. It is more convenient to look at the landmark itself at the bottom of the antenna structure itself, along the L-shaped converter holder (as if aiming) .
Alas, no matter how hard we try, it is practically impossible to immediately install a satellite dish strictly in accordance with the azimuth (although in practice, this has happened). Therefore, our next task will be to expand the range of the expected location of the satellite.
Let's take this option as an example. There are two houses located not far from each other, and the landmark will be a tree standing almost between them (Fig. 3).
Rice. 3. Setting the direction of the satellite dish, choosing a landmark.
The picture shows, let's say, the ideal option. In practice, of course, all this can be completely different, but, for example, I think this option will be enough
Since we have determined only the approximate direction to the satellite, we cannot say that our landmark is located exactly on one vertical line with the satellite itself, then we will have to slightly expand the search range (Fig. 4).
Rice. 4.
That is, we need to minimally expand the search range, but at the same time, be sure that the satellite itself is located in this range, the limit of which will be the two extreme landmarks. In this case, our two extreme landmarks will be the edges of two houses adjacent to our tree.
Now, let's look at another option. Where the tree itself, in the direction of which the satellite we need hangs approximately, stands closer to one of the houses. Here, the range can be taken starting from the second from the edge of the window of one house, and the edge of the corner of another house (Fig. 5).
Rice. 5 Selecting the tuning range of the satellite dish to the satellite.
Satellite dish tilt angle
(pre-setting the initial tilt of the satellite dish)
We have decided on the horizontal search range. Now, let's look at the vertical initial position of the satellite dish, that is, its tilt.
I have already talked about how to determine the tilt of a satellite dish earlier.
According to the coordinates of my location, the tilt of the satellite dish will be 73.20° from the horizontal plane, or if measured by the declination angle, then 16.80° from the vertical plane (Fig. 1).
Rice. 1
Since it is not possible to immediately establish the exact tilt of the satellite dish mirror (there is no place to get a reference point from), we, in principle, do not need to know the exact data of this angle at all. I gave all the explanations and drawings so that you can roughly imagine what vertical position your satellite dish should be in. This will be useful if, for example, you tilted the antenna mirror too much (or raised it), then you immediately realized that the antenna should be moved back.
Now, we need to set the initial angle of inclination of the satellite dish mirror, from which we will begin the vertical adjustment. In my case, I will install the antenna mirror above the desired angle, about half (Fig. 2).
Rice. 2
Then, when setting up the satellite dish, I will lower its mirror in small steps until a signal appears. You may have a question, why exactly did I initially raise the antenna, and when tuning, lower its mirror down, and not vice versa? The point here is that the satellite dish itself, under its own weight, tends to lower its mirror down. And if we gradually raise it rather than lower it, then due to the play in the bolted connections, the antenna will move back a little, thereby making it difficult for us to adjust later.
Decide in what vertical position your satellite dish will be placed, and apply the above to your case.
If you don’t know what slope the mirror of your satellite dish will have, then you can put it in a vertical position, and also gradually lower the mirror (or if you live close enough to the equator, raise it) until a signal from the satellite appears. But this again will increase setup time.
Well, I think now it’s time to move directly to the search for a satellite, that is, to step-by-step setup horizontal and vertical position of our satellite dish...
Before you start setting up a satellite dish, that is, before searching for a signal from a satellite, check all cable connections. Don't forget to check that you have correctly connected the coaxial cable from the converter to the receiver. It should be connected to the connector with the inscription - IN(Photo 1), that is " entrance". In this case LNB IN- converter input (LNB - converter designation).
Photo 1. The cable must be connected to a connector with the initials - IN.
Attention! Since there is a difference voltage between the converter and the receiver (even when it is turned off), in order to avoid their failure, connect and disconnect the coaxial cable only when the receiver’s power is turned off (while touching the plug to the connector, a discharge spark may slip through).
Having connected all the cables, turn on the receiver, and then go to the menu where an indicator of the level and quality of the signal of the selected transponder is displayed. Since the satellite dish has not yet been configured, the indicator readings will be at zero (the indicators of some receivers may show a low signal level, that is, the level of the receiver or converter’s own noise).
The fasteners on the suspension device, that is, those fasteners that are responsible for the horizontal and vertical movement (Photos 2 and 3), should be slightly tightened. We will do this so that in the future, with little effort, we can move our satellite dish.
Satellite dish fasteners
Satellite dish mounting mounting bolts (option No. 1).
Satellite dish mounting mounting bolts (option No. 2).
Next, let's come to the design of the satellite antenna itself, and stand so that you can simultaneously move the antenna mirror and look at the TV screen. As I explained earlier, we need to observe the readings of the signal level and quality indicator, as in the example of receiver No. 1 (Photo 4 and Photo 5).
Preparing to set up a satellite dish
Before we begin setting up a satellite dish for a satellite, I think it would be useful to explain one more point regarding the input of existing transponders into the satellite receiver.
Satellite coverage map
Let's imagine such an example. The satellite receiver is correctly configured for the satellite antenna configuration (the correct parameters of the converter installed on the antenna are entered), and the parameters of the entered transponders of the selected satellite contain valid values. Further, when you try to tune a satellite dish to a signal from this satellite, no matter how you twist the mirror of this antenna, there was no signal. Why?
The point here is that any satellite also has such a parameter as the satellite signal coverage area, which I already mentioned earlier, that is, this signal can only cover a certain area of the earth’s surface. And if we enter even valid transponders into the satellite receiver, then the signal from the selected satellite may simply not cover the area of the earth’s surface where your particular settlement is located. Well, of course, there can be no talk of any signal reception from this satellite.
So, before tuning the satellite dish to the selected satellite, be sure to check not only whether the transponders are valid, but also check on the coverage map of the selected satellite whether your locality is included in this coverage area. That is, whether the selected satellite, with its beam, covers your geographic coordinates.
Express AM 22 53.0°E satellite coverage map from the website www.unionsat.ru
Using the table, we find the diameter of the satellite antenna, which corresponds to the given power. It is equal to 0.95 meters. I took 1.1 meters, that is, a little with a margin.
At the next, quite important stage, we have to configure the satellite dish to the signal from the selected satellite. Therefore, a little about life...
Alas, no matter how much I would like to talk about it, but as practice has shown, it is at this stage of setting up a satellite dish, after several unsuccessful attempts, that novice tuners lose all interest in the setup itself. Here, don’t get me wrong, I’m not talking specifically about you.
But still, if this happens, do not despair under any circumstances, because even an experienced tuner can make the simplest mistake. Be sure to check all cable connections and the settings you entered into the satellite receiver. And of course, be sure to try again.
It happened, more than once, that I heard something like this: “...what am I...”, “it turns out there, all that happened...” and so on.
Remember, to set up a satellite dish, you do not need to have any “normal” abilities, or any special gift from nature. YOU can do all this YOURSELF!
Searching for a satellite signal
Now, as I explained earlier, the direction of the satellite dish mirror, horizontally, should be in one of the extreme positions of the range of intended landmarks, for example, in the left. In Fig. 1, in this direction, a red vertical line is drawn.
Rice. 1 Start searching for a satellite signal.
If you have not determined the horizontal range in which the desired satellite is located (for example, you have not found landmarks), deflect the satellite dish mirror based on compass readings, plus a small margin. For my case, this is the situation I indicated in Fig. 2. I indicated the initial horizontal position of the antenna with a green arrow. This example, of course, is suitable for my location, since in your case, the direction to the satellite may be different.
Rice. 2 Initial horizontal direction of the mirror satellite dish.
Vertically, as I explained earlier, before searching for a satellite signal, the satellite dish must be tilted, approximately half the angle of inclination to your area (Fig. 3).
Rice. 3
If you also do not know the tilt of your antenna, then place it in a strictly vertical position (Fig. 4).
Rice. 4 Tilt the satellite dish before searching for a signal.
The general principle of this satellite dish setup is to scan a certain area of the sky with the antenna mirror, although this sounds strange, but in fact, this is exactly the case. To be more precise, we need to scan that part of the sky in which we are absolutely sure that the desired satellite is located there.
We will begin the search for a satellite by rotating the satellite antenna mirror in a given search range in the horizontal plane, while starting the movement of this mirror from one landmark and ending with another. In Fig. 5, I indicated the edges of the search range with blue arrows.
Rice. 5
If you have not decided on the search range, then, guided by the compass readings, begin a horizontal search for a signal from the satellite, from the position that I showed on the previous page (in Fig. 3) to approximately the same position (as if in mirror image), on the other hand (Fig. 6). This method is usually used by more experienced installers.
Rice. 6
But, be that as it may, in both cases, you must be sure that the satellite is located exactly in the search area. If you are not sure about this, then be sure to expand it.
Since our satellite antenna looks with the plane of its mirror towards the extreme position of the selected range, we begin to slowly rotate it around the support pipe, from right to left (Fig. 7). You can, on the contrary, start from the other edge of the search zone, as you wish.
Rice. 7 Let's begin to slowly rotate the satellite dish mirror around the support pipe.
Here, I want to explain some important points related to this stage of setting up a satellite dish.
Each satellite receiver, when a signal appears at its input, has such a disadvantage as inertia, that is, it needs time to process the data stream from the satellite. Therefore, if you move the satellite dish mirror too quickly (!), the receiver will not have time to process it, and you will miss the desired point. Please take this into account when setting up your satellite dish at this stage.
Searching for a satellite signal (end)
Having reached the edge of the satellite signal search area, lower the satellite dish mirror by about one degree, and similarly move in the other direction. And again, we reached the edge, lowered the antenna mirror... etc. Do not forget, while doing these manipulations, to look at the signal level and quality indicator. Continue this way until the signal itself appears. I schematically depicted the trajectory of the satellite antenna mirror below in the figure (Fig. 8).
Rice. 8 The procedure for searching for a satellite signal.
If, with such actions, you do not end up in the very center of the satellite signal flow (Fig. 9), then your satellite receiver will still show some level of this signal.
Rice. 9 The procedure for searching for a satellite signal, the possible location of a satellite.
Usually it goes like this. While the satellite dish mirror is moving, at some point, the receiver sharply shows the signal level, and this signal disappears again. In this case, move the antenna even more quietly, but in the opposite direction, until a stable level of the satellite signal appears.
If, after scanning the entire area, you still do not receive a satellite signal, then return the antenna to its original position and repeat the entire procedure again.
At this stage of setting up a satellite dish, very common mistakes are:
- The satellite dish mirror moves too quickly, and the receiver itself simply does not have time to process the signal from the satellite (that is, the data that this signal carries).
- They lower the satellite dish mirror in too large steps. In this case, the proverb fits well here - “The slower you go, the further you will go.”
If, when searching for a satellite signal, you made several attempts, and still did not get a signal... Then below, I will list possible mistakes and problems:
- The transponder entered in the receiver settings is not valid.
- The signal coming from the satellite you have chosen does not cover the coordinates of your locality. That is, the coverage map of the selected satellite has not been verified.
- The polarization of the satellite signal is incorrectly set in the receiver settings.
- There is no line of sight between the satellite and the satellite dish. For example, a neighbor's house or a tree next to your house may be an obstacle.
- The coaxial cable is not connected correctly to the receiver (to the wrong jack).
- A converter is installed on the satellite dish, which does not fit frequency range, or type of polarization.
- The diameter of the satellite dish is too small to receive a signal from this satellite.
- There is a short circuit in the connecting “connector-connector” of the coaxial cable (a hair of the cable braid gets onto the middle core).
- The search area is incorrectly selected (the wrong direction is selected).
- The converter, on its holder, stands crookedly (turned sideways around the axis of the “L-shaped” holder). In principle, in this position, reception is possible, but if the signal power from this transponder is weak enough (to be received by the diameter of your antenna), then it will be difficult to catch it. The position of the converter around the axis of the holder is quite critical for receiving a signal in horizontal and vertical polarization . A converter with circular polarization, in principle, does not need such an adjustment, and it will be enough to simply place it vertically.
- The satellite converter or receiver may be faulty.
In my experience, as well as the experience of my friends, a malfunction of a satellite receiver or converter is a very rare occurrence. There were cases when, for example, the converter gave weak signal, or after rain it stopped working normally (defect in the seal of the housing). In principle, equipment malfunction is the last thing to think about. Be sure to check and double-check everything, and check and double-check everything again, and only then blame the equipment.
Further, I will assume that you received a signal from the selected satellite, and both level and quality appeared on the signal level and quality indicator. Below in the images, I have provided photographs of indicators satellite receivers with the presence of a signal, which I have already shown earlier.
Now, we need to more accurately adjust the satellite dish mirror to the maximum signal level. To do this, constantly watching the TV screen, that is, the signal level and quality indicator, tilt the mirror satellite dish right and left, up and down. At the same time, ensure that the indicator readings are as maximum as possible.
The procedure for tightening the bolts and nuts of the satellite antenna suspension
As soon as the signal level is at its maximum, we need to tighten the mounting screws. This must be done with caution, so as not to disrupt the previously carried out setting up a satellite dish. I have indicated the desired order of tightening the nuts and bolts in Photo 1 and Photo 2.
It is advisable to tighten the fasteners (nuts, bolts) that press the suspension itself to the support pipe simultaneously. Since it is practically impossible to do this at the same time, we do it this way. We tightened the first nut or bolt one half turn, then the second one, and so on.
In the first option (Photo 1), in more detail, the order of tightening the nuts is as follows - tighten one, or half a turn 1 - 2 - 3 - 4, then again 1 - 2 - 3 - 4... and so on until you press the suspension to support with sufficient rigidity. We tighten the bolts or screws with nuts for the vertical movement of the suspension (5) last (also one by one, half a turn).
In the second option (Photo 2), after tightening the fasteners of the suspension to the support, first screw in screw with nut 2 (which stops the vertical stroke of the suspension) until it stops, and only then 3.
While tightening the nuts, constantly monitor the signal indicator readings; if the level drops a little, slowly unscrew the nut that was being turned at that time, and begin to tighten the other one in the same way. In general, ensure that when the gimbal is securely fastened, the signal level remains at the same maximum level as before tightening the nuts.
And so, setting up the satellite dish mirror to the desired satellite is complete!
Next, in order to squeeze the maximum signal level out of the diameter of our satellite dish, it’s time to start adjusting the position of the satellite converter...
Satellite TV is good decision in country and low-rise buildings. Everywhere where cable TV and Internet television operators do not work. Satellite kits, including all the necessary equipment, can now be purchased even in supermarkets selling equipment and electronics. Once you have decided on the operator, tariff and purchased equipment, you must configure the satellite dish yourself or with the help of technical specialist operator.
The essence of satellite TV technology is as follows:
- The signal is transmitted from a satellite above the Earth, moving in orbit, but not changing its position relative to the Earth.
- The satellite dish is pointed directly at the broadcasting satellite.
- The satellite signal focused by the antenna is transmitted to a converter, which turns it into electrical signal and transmits it to the receiver.
- The receiver can be external or built into the TV. All modern TVs are capable of receiving a signal from a converter without additional equipment.
The satellite antenna itself is universal and, with a sufficient diameter, is suitable for any operator. The only difference is in the equipment and its setup. The leading providers of satellite TV services in Russia are Tricolor and NTV+. They both broadcast from the same satellite, so their setup and installation will be similar.
Tricolor and NTV+ are paid and to access the found channels you need a special card, registration and payment for one of the types of subscriptions. But there are many satellites broadcasting free channels, including in Russian. You can choose and configure the antenna to one of them, or purchase several satellite dishes, or use the rotating mechanism for convenient reorientation.
Installation and configuration of a satellite dish for Tricolor and NTV+
Since Tricolor and NTV+ broadcast from the same satellite, the algorithm for installing, configuring and connecting the antenna to the TV will be the same:
- To get started, purchase satellite dish sufficient diameter.
- Buy equipment to receive a signal from a dish:
- receiver and access card (for NTV+), from 5,000 rubles.
- if you have a TV with a CL+ connector, then you can purchase a special module and card (for NTV+), from 3,000 rubles.
- digital two-tuner receiver (for Tricolor, from 7,800 rubles) or a ready-made kit together with a Tricolor dish with a TV module (8,300 rubles) or a receiver that allows you to later connect 2 TVs (17,800 rubles).
- You can purchase any receiver yourself, having first checked its compatibility with the operator’s signal on the website or in the technical support service.
- When all the equipment is ready, you can begin installation. For the European part of Russia, the satellite is located in the south, so the antenna must be installed on the southern part of the building.
- There should be no obstacles on the signal reception line. Try to mount the plate higher.
- Attach the bracket to the wall using anchor bolts. It should be screwed tightly and not wobble.
- Assemble the plate according to the instructions for it and secure it to the bracket.
- Place the converter on the special holder and attach the cable to it. It is better to install the converter with the connector down to avoid precipitation.
- Now you need to connect the receiver to the converter and the TV. If you are using a module, then insert it into a special connector, and connect the cable from the antenna to the TV.
- Turn on the TV and receiver. Antenna installation is complete. Next, you need to tune it exactly to the satellite and search for channels.
In the case of NTV+ and Tricolor, which broadcast from the same satellite, no additional equipment is required for setup. Once the south direction has been installed, make fine adjustments:
You can also use special tables that show the approximate location of the dish in angle and azimuth for different cities of Russia. Such tables are easy to find for Tricolor, NTV+, and, if desired, for other satellites.
Free satellite channels
In addition to Tricolor and NTV+, you can set up your antenna for other satellites that broadcast channels for free. To do this, you will need any receiver or TV with a built-in signal receiver. An access card and, accordingly, a module for the card are not needed, since you will tune in to unencrypted channels.
In Russia, you can connect the antenna to the following satellites:
- Astra 4a 4.8°E;
- AMOS 2/3 4°W;
- HotBird 13°E;
- ABS 1 /1A /1B, 75°E;
- Intelsat 15 85.2°E;
- Yamal 201 90°E.
The procedure for installation, configuration and connection is similar to that used with NTV+ and Tricolor. But in order to correctly point the antenna at the satellite, it is better to use special program, such as Satellite Antenna Alignment.
Satellite Antenna Alignment can be downloaded free of charge for non-commercial use from the official website http://www.al-soft.com/saa/satinfo.shtml. Main characteristics and rules for using the program:
- Launch the program and enter the coordinates of your location in the Site Location window. You can find out these coordinates on any smartphone or tablet with GPS or on special websites on the Internet.
- A list of satellites with azimuth and tilt coordinates will be displayed on the left.
- If the angle values are negative, it means that the satellite is below the horizon and communication with it is impossible.
- Using the program data, you can easily set the antenna position without a compass. The “sun adjustment” function is designed for this:
- Select the satellite you want to point the dish at.
- Go to the Sun's Azimuth tab.
- On the right side of the window you will see the current position of the sun. Here the program calculates on what day and time the position of the sun will coincide with the position of the satellite.
- At the indicated time, simply point the antenna towards the sun.
By entering your satellite dish data in the Offset antenna tab, you can accurately determine the level of inclination you need.
Satellite Antenna Alignment - program window
After you have pointed the antenna to the desired satellite, you need to connect it to the TV and configure it as indicated above. To make it easier to tune to a strong signal, you can use a device such as a satellite finder. You can buy a simple switch for around 400–500 rubles, or you can buy a more expensive one with a display and various functions, their price starts from 2000 rubles. To use Satfinder:
- Connect the satellite finder between the converter and the receiver approximately 1–1.5 meters from the converter. The cable from the converter is connected to the LNB connector, and the one that goes to the receiver is connected to the REC connector.
- Go to the receiver’s “Signal Level” menu.
- Proceed with fine tuning, following the movements of the arrow on the satellite finder. If the direction is correct, the arrow will move to higher values.
These are the basic rules that you need to follow in order to successfully install, connect and configure a satellite dish yourself. The procedure is simple, but it will save you money that you would have paid for a specialist to visit you. The main thing is to handle the antenna carefully, securely fasten it in the correct position and follow all steps of the installation instructions. Share your ideas in the comments on how else you can simplify the process of installing and configuring a satellite dish in an apartment or house.
Setting up an antenna for receiving television channels from satellites ABS1, Express AM2, Yamal 201 using a multifeed.
1. Collect multifeed, according to the attached drawing.
(The location of the converters is indicated for a 0.9 m antenna. For a 1.0 m antenna, the distances between the converters should be slightly larger)
2. Install angle of inclination of the converters so that they look at the center of the antenna mirror
The above distances between converters are approximate. In each specific case, they may differ slightly and are determined locally, for a specific antenna and according to the maximum signal level.
3.
Collect antenna according to the assembly instructions. The multifeed with converters is mounted with a central support in place of the standard converter mounting. To securely fasten the multifeed, you may need to drill 2 holes in the sleeve. Firmly secure the support at the selected point. When installing on a balcony or loggia, the fence is drilled through and the support is attached with ordinary long bolts of large diameter. When installing on a wall, holes are drilled in it and self-propping anchor bolts are used.
4. Having mounted antenna, you should immediately turn it in the direction of the sun’s position at approximately 12-14 o’clock in the afternoon, and install it vertically, relative to the support.
Often there are some obstacles in the direction of the satellite that can interfere with signal reception.
It should be noted that any obstacles, including window glass, not to mention trees and bushes, located in the path of the signal can make it impossible to receive it.
5. Installing antenna and pointing it at the location where the satellite is supposed to be located, lightly secure it to the bracket, but so that it can rotate on it with little effort. The setup process is greatly simplified by installing a clamp under the antenna mount on the bracket. In this case, the mounting bolts can be loosened to such an extent that the antenna will rotate freely, supported by the clamp.
6. Then, having connected the receiver and the central converter (Express AM2) with a cable (initially, all settings should be made directly, without connecting the drives), proceed to setting up the antenna. Antenna tuning consists of several stages.
Initial setup of the antenna for the central satellite:
To configure the antenna for the central Express AM2 satellite, you should enter into the receiver the parameters of the transponder on which you will search for the satellite.
Frequency - 11606, polarization - vertical, flow rate - 44948.
In most receivers this is done as follows:
Enter the Menu, select "antenna installation" or "transponder search" and enter the appropriate transponder parameters.
You can configure it on any satellite from the list. It is not this that is important, but the correctly entered value of the transponder parameters. Be sure to check what type of converter (LNB) is installed in the settings. In this case, the converter type must be “Universal”, or in some receivers “Single”. If you choose the right converter type, you should have the following local oscillator frequencies: 9750/10600.
Next, use the digital buttons on the receiver's remote control to enter the above transponder parameters. The setting is made using the menu item "Signal Level" (Scan, etc.). Modern tuners usually have 2 level scales. The first scale - "Level (Signal)" - shows the IF level at the tuner input. The second - "Quality" - shows the level of the useful signal with the specified parameters (frequency, speed and FEC). The level on the first scale includes both the useful signal from the satellite and the noise of the head, on-air noise, and the noise of all devices on the path from the head to the tuner. Most often, before connecting the head, the level is “0” and becomes greater than zero when it is connected. Some tuners have only one scale, but often when a useful signal is captured, the color of the scale changes, for example, it turns from gray to yellow. The initial search is carried out on the first scale. The level on it increases as it approaches the satellite. The search is carried out by scanning the sector in which the satellite is supposed to be located. It should be borne in mind that obstacles, such as a nearby tree, the sun, or just a hand, also increase the signal level on the first scale. But it will be impossible to receive a satellite through them. When the tuner receives a signal from the satellite, the level on the second scale will appear - “Quality”. Further adjustment is carried out on the second scale according to the maximum signal. The scale may be located in another menu item and, depending on the brand of the receiver and the version serving it operating system, be positioned vertically or horizontally. One thing is certain: when the “LNB power supply” option is disabled, the scale will indicate null value. You should scan starting from the position in which you have the antenna installed, slowly rotating left or right 10-15 degrees in different directions. You need to rotate it quite slowly, because digital signal is not processed as quickly as analogue, and appears on the TV screen with some delay. As soon as you catch a signal, the bottom bar will also color. In this case, you should very carefully turn the antenna to achieve the maximum signal level in the lower strip.
If you did not catch the satellite in one pass, then raise the antenna a little up or down and repeat the operation. You may have to do this procedure several times.
The final indicator of correct satellite tuning is the presence of a picture on the TV screen. It happens that on nearby satellites some frequencies coincide and tuning the antenna based on the presence of a level in the lower band in the menu does not lead to tuning to the desired satellite. Therefore, having configured the antenna in this way, before final tightening the fastening nuts, you should make sure that the picture is present.
Having achieved the maximum signal level, proceed to the final tightening of the fastening nuts. They should be tightened carefully, all the time monitoring the signal level on the receiver scale, since in this case the antenna moves slightly in one direction or another depending on which side you tighten the nut.
Then Having finally secured the antenna, you begin setting up the remaining multifeed converters. By connecting the receiver with a cable to the converter located to the left of the central converter (when viewed from the antenna side of the multifeed), enter the parameters of the ABS1 satellite transponder.
Frequency -12640, polarization - vertical, flow rate - 22000 .
Next, if there is no signal quality scale, loosen the converter mounting bolts and move it up and down in different directions until the signal value appears on the quality scale and its maximum level.
After setting up this converter, proceed to setting up the converter located to the right of the central converter. This converter is designed to receive a signal from the Yamal 201 satellite.
The transponder parameters for configuration are as follows:
Frequency – 11057, polarization – vertical, flow rate – 26470.
Having configured the multifeed, connect all three converters with the disk using the supplied short cables, in accordance with the attached figure.
In the receiver settings, you should bring the port parameters in line (select the corresponding numbers in the Diseqc 1,1 menu: ABS1 - 1, Express AM2 - 2, Yamal 201 - 3) with connecting the cables to the disk.
Then you should make automatic search satellite channels. If not all channels are found as a result of the search, then you should switch to manual search mode and conduct a search by entering the parameters of the missing transponders. Below is a table with a list of channels.

Modern television broadcasting systems are developing at a rapid pace. To replace analog terrestrial television Digital broadcasting is coming. It provides excellent image quality, eliminating channel overlapping, picture distortion, the appearance of “snow” on the screen and other interference. Along with improving the quality of terrestrial television broadcasting, systems satellite television.
Do you need satellite TV?
Satellite television greatly expands the consumer's ability to watch television channels. It is the source of a huge variety of TV channels broadcast in almost all languages of the world. However, many channels are available for free viewing.
Satellite television is relevant in areas where there is complex natural terrain, or in areas of dense high-rise buildings.
As is known, meter and decimeter waves of terrestrial television broadcasting are not able to bend around spatial barriers. They are reflected from any object and create additional television interference. Satellite television makes it possible to receive a signal directly, excluding the impact of artificial and natural barriers.
Another advantage of satellite television is the ability to capture television broadcasting zones in regions where the distance between settlements is enormous and the organization of continuous coverage is impossible.
It is also important that even a non-professional can install a satellite dish on his own without calculations and special equipment.
Advantages of satellite television
Perhaps the most important advantage is the relatively low price for equipment, which will pay for itself in a short period of time, due to the absence subscription fee for watching TV channels.
The big advantage of satellite television is excellent video and audio quality, not inferior in characteristics to the best DVD.
How does satellite TV work?
In the direction of the southeast, south and southwest above the equator, at the same place relative to the Earth, satellites are located that receive the signal from the television broadcasting center.
The received signal is transmitted by satellites to Earth, covering large areas like the beam of an electric searchlight. In this case, the signal level itself decreases from the center to its edges.
It should be noted that the signal does not pass through natural and artificial barriers, such as walls, buildings, trees, etc. This factor should be taken into account when choosing a location to install the antenna.
The satellite signal is focused onto the convector using an antenna. After undergoing primary processing, it is transmitted to the receiver via antenna cable. The receiver converts it to a television channel and then transmits it to the TV.
Antenna operating principle
A satellite dish is a round dish-shaped parabolic structure. She independently receives microwaves from satellites broadcasting signals from television communication sources.
The parabolic shape of the offset dish reflects the incoming signal to an antenna mounted in the center of the structure. An automatically adjustable horn feed is attached to the dish coordinator. This part is an amplifier of the received signal. Front convector heads carry out selection of radio waves from the focal point, with transmission to the downconversion block. The role of the horn is to convert radio waves and electromagnetic signals into electrical ones. Additionally, their spectrum is adjusted. The signal from the convector goes to the receiver, and then to the TV.
Types of plates
There are two types of satellite dishes:
- offset;
- direct focus.
The principle of installing offset dishes lies in their orientation below the satellite broadcast line. The signal is reflected by the plate and hits the converter at an angle.
The offset plates are mounted almost vertically, which eliminates the accumulation of precipitation in the structure that can affect the quality of signal reception.
In direct-focus designs, a significant part of the mirror is covered by a convector. As the diagonal increases, this becomes almost unnoticeable.
Antenna installation location
If you plan to install satellite dishes yourself, then certain rules should be followed:
- there should be no obstacles (trees, buildings, structures) in the path of signal reception;
- The initial direction of the antenna is south.
Satellite TV set
The standard set of equipment consists of six items:
- satellite dish. Serves to receive a signal from a specific satellite;
- bracket. Necessary for attaching the plate to a building or support;
- convector Converts the signal received by the dish and sends it to the receiver;
- disek. Serves to connect two or more convectors;
- connection cable. Transmits a pre-processed signal to the receiver;
- DVD tuner. It is used to convert the signals received by it into television signals.
Preparing to install satellite equipment
We determine the location of the cardinal points using a compass and select the optimal place to mount the antenna. Please note that placing the antenna on the roof of a multi-story building may provoke its theft, and permitting documents may be required for mounting on the facade. To self installation Since satellite dishes have not become a problem, these issues should be resolved in advance.
The satellite dish assembly itself is not something out of reach. The attached instructions describe in detail how to install the satellite dish yourself.
The installation procedure is as follows:
- assemble the plate according to the instructions;
- assemble and secure the bracket taking into account natural loads and wall material;
- secure the convectors in special holders with the connectors facing down to prevent moisture from getting inside;
- connect the receiver and convectors with a cable using F-connectors. You must leave a meter of cable near the antenna;
- securely fasten the cable to the holder arc;
- seal the connectors with silicone or sealant;
- fix the antenna on the bracket, leaving the possibility of moving vertically and horizontally.
Preparing the cable involves connecting it to the F connector. To do this job you will need a mounting knife and pliers.
Installation of F-connectors
To connect the connectors correctly, follow the following sequence:
The connection cable is ready. Now you can start setting up the antenna. Of all the work carried out self-configuration satellite antennas are more labor-intensive and responsible.
Make sure the antenna is installed correctly and facing south.
Making settings on Sirius. Setting up satellite antennas yourself begins with setting the frequency 11766 and speed 27500 on the receiver. Select polarization “H”.
We see two bands on the receiver:
- red – displays the connection of the dish and satellite signal;
- yellow – shows the level of the received signal.
If the antenna is connected correctly, the signal level reaches 40%. In this case, the signal quality is zero.
We are approaching the culminating question of how to set up a satellite dish yourself. Set the initial position of the antenna all the way to the left and up.
Then carefully turn from left to right and control the level of signal quality. If it is absent, lower the plate 2-3 mm down and repeat the procedure in the opposite direction - from right to left until it stops. We carry out this algorithm work until a yellow stripe appears.
We control the tilt of the plate using specially marked numbers on its fasteners.
At this stage It’s difficult to orient the plate yourself at altitude and simultaneously monitor the appearance of the signal on the receiver. Therefore, it is necessary to involve an assistant in the work.
If the yellow bar indicator is within 21%, we fix the position.
We carry out more precise adjustments
Lowering the antenna slightly, we make a slight turn to the left. If the signal quality has deteriorated, we return to the starting position. We make a turn to the right, as well as up and down.
When the signal reaches 40%, we proceed to setting up the convector. We rotate first clockwise and then counterclockwise and achieve a signal improvement of up to 65-70%.
Setting up side convectors
Once the main plate is set up, the side convectors are much easier to set up.
We configure on Amos. On the receiver we set the frequency to 10722, speed to 27500 and polarization “H”.
For Hotbird the frequency is 11034, the speed is 27500 and the polarization is “V”.
The setup procedure follows the example of Sirius.
By bending the side brackets from the left top corner to the right and gradually lowering by 2-3 mm, we achieve the appearance of a signal.
To improve the signal quality, we rotate the converters around their axis. First rotate clockwise and then counterclockwise.
So we figured out how to set up a satellite dish yourself. With some experience and a work plan, this is not difficult to do.
After final antenna setup, carefully secure the cable and turn on the SCAN function on the tuner. The tuner will independently scan the TV channels available for viewing and display a list of them.
After this, you can start watching TV shows.
Information technology currently amazes with its rapid pace of development, providing more and more opportunities to modern man. Despite the gradual development of Internet television, satellite broadcasting remains in first place in terms of popularity and quality of broadcasting, since it can provide a clear picture of a digital image at any time of the day or night. This is why many people think about how to set up a satellite dish and whether it is possible to do it themselves. The answer here will be in the affirmative, since it is quite accessible to every person, subject to careful study of the technology for setting up satellite equipment.
So, first of all, you should remember that the most popular satellites that broadcast today are 73 Russian speaking channel are Sirius, Amos and Hotbird. The main advantage of installing a dish is its price, since sooner or later you will fully recoup the cost of the satellite equipment. After all, most television channels are broadcast without encoding and are therefore completely free.
How to set it up and what is needed for this? To shed some light on this issue, let's start with a standard satellite dish kit:
- Mirror (dish) - used to receive a signal from a satellite, and can have dimensions from 60 to 129 cm in diameter.
- Converter is a device for transcoding a signal to the frequency with which the next device, the receiver, operates.
- DVC - Receiver - directly receives the decrypted signal from the converter and transmits it to your digital device(TV, plasma and so on). In addition, the standard delivery package also includes DiSEq (disek), a device for connecting several converters into a single unit, as well as cables and brackets. And, of course, you should not forget about high-quality mounting devices, with the help of which you will need to point the dish at the satellite in the south-west direction.
There are many manuals where you can find the answer to the question of how to set up a satellite dish yourself, but if you analyze many of them, then all the work can be reduced to several stages:
1. Preparing equipment for installation. At this stage, according to the instructions, you assemble the plate itself, attaching brackets and all other technical parts to it. The important thing to note here is that you must carefully connect the “F” cable to the connector located at the bottom of the dish on the receiver. Having opened the lid, we will find there a screen in which there will be several connectors, into one of which we install a cable. After this, the converters are connected to the disk drive, which, in turn, is attached through a special connector to the receiver.
- How to set up a satellite dish to receive a good and high-quality signal? Now we proceed to the most important part of the entire operation - setting up the satellite dish. So, we set up the reception frequency for the Sirius satellite, for which we set the speed in the receiver to 27500, frequency 11766 with polarization “H”. The receiver has two signal reception bars - red and yellow. The first shows the connection of the dish and the signal level. The yellow stripe determines the quality of the supplied signal. Usually, immediately after connection, the last red bar shows the signal somewhere around 35-40%, and the yellow one approaches zero. After this, it remains to adjust the signal quality by rotating the plate to find the most acceptable position for the signal. You should turn the receiver adjustment plate until the signal quality increases to 65-70%, which will guarantee you a high-quality image in any weather. Thus, we now know how to set up a tricolor satellite dish. To further enhance the signal, you should adjust the side convectors by setting the appropriate frequencies (Amos - frequency 10722, polarization “H”, S speed 27500; for Hotbird frequency 11034, polarization “V”, speed 27500). After this, press the SCAN key on the receiver, and the system will automatically find and save all possible channels for you.
Now the question of how to set up a satellite dish is not difficult for us, since, knowing the features of installing the equipment of the entire system, correct setting You can also make it yourself.
Happy viewing!
