Set up satellite dishes yourself
The satellite television system is a supply complex, the main purpose of which is the reception of television programs. This broadcast is performed using special communication satellites located at their location - the equatorial area.
This type of television is becoming more common. And millions of families own satellite dishes. For their installation and connection most often enlist the help of professionals. But the ordinary person setting up satellite antennas is possible. You do not need to have special skills or knowledge. Self-tuning of a satellite dish is not so difficult, the price of which, even without paying for the services of a specialist, is essential for an ordinary person.
Choosing a satellite
After it was decided to self-install and configure the satellite dish, you need to decide on the satellite. This means that you need to choose the operator of this type of television, whose signal it will receive.
The name of this television originated due to the fact that a whole system of orbital satellites in space is used to support it. They transmit the signal received from television stations to vast territories located on Earth.
Satellite dishes are sort of its receivers. After the signal is received, it is reflected on the collecting head, which is called the convector. He sends it to the receiver - a device for configuring satellite antennas and decoding. And only after passing through all these stages, it gets on the TV screen as an image and sound.
Types and placement of satellites
There are 2 types of satellites. Some are used to broadcast open channels, others are coded. There are cases when the owners of the equipment on the satellite are different operators. Then self-tuning satellite dish provides for the acquisition of a special card in order to decode each channel separately. But in most cases the group of channels makes a package. And to restore access to them, it is enough to have a single card.
Russian-language channels are broadcast from different satellites. They are located at different latitudes and meridians. To ensure reception of a signal from a selected source, it is necessary to direct the antenna precisely at it and correctly adjust the reception frequency. If the selected satellites share a considerable distance, you can receive a signal from them with just one antenna.
In the selection process, you need to consider whether it is possible to send your antenna to a specific signal source. If any objects (neighboring buildings, trees, etc.) will create significant obstacles to its entry, you need to install it on the roof of the house. If this possibility is absent, it is necessary to try to tune the antenna to other satellites located in sight.
It is not difficult to guess that one antenna and its signal is not enough. In order to configure the satellite antenna with your own hands, you need to have, properly install and configure the whole system of satellite equipment. It can be purchased at a specialty store.
The main elements for assembly:
- Antenna, which is often called the "plate". Its diameter is from 0.7 m to 1.2 m.Its purpose is to form the received beam into focus.
- The most expensive part is the receiver. His choice should be approached with great care and responsibility, because the broadcast is divided into two formats: mpeg2 and mpeg4. The second is much better.
- Head, which is a convector. Their number can vary from 1 to 3. Depending on the number of satellites, one for each. They should be universal with a linear type of polarization.
- 2 mounting (multifeeds).
- Switch Converter - Dis. Its presence is due to the fact that the tuner assumes simultaneous reception of a signal from only one satellite. And Diske - a device for configuring satellite antennas - provides switching in the case when 2 or more are used.
- Coaxial cable with 75 Ohm impedance. His number must be calculated so that there is a margin of 3-5 meters.
- Plugs used to make the connection (F-connectors).
- Bracket and dowel.
Installing and configuring a satellite dish do it yourself with the following tools:
- extension cord, designed for at least 3 sockets;
- drill or perforator (used to fix the bracket with dowels);
- 10 and 13 mm wrenches;
- cross-head screwdriver;
- insulating tape or plastic screeds.
- When assembling the antenna, it is necessary to carefully tighten the bolts, and do not drive washers and engravers.
- Attach the bracket to the wall.
- Hang an antenna on it so that it is turned to the south or southeast. You can also see where she "looks" from the neighbors.
- Stretch the extension cord and take along the tuner and TV.
- Connect the TV, receiver and antenna central convector (one, directly to the receiver).
- Configure the entire system.
Proper setup of satellite dishes depends on the choice of location for their installation. In this case, you need to take into account several nuances. In order to receive the signal from the satellite, it is necessary that it freely fall on the receiving mirror. Therefore, it is necessary to install the antenna as high as possible. For this ideal rooftops.
Program for configuring satellite dish "Satellite Antenna Alignment"
In order to correctly calculate the elevation (elevation angle) and the azimuth of all the satellites separately, use the program Satellite.It differs from other similar services in that it determines these characteristics for all satellites simultaneously. You can immediately see which of the satellites are available at a given antenna location, and which ones are not.
But here the calculation is purely theoretical. But in practice it is necessary to take into account many factors and interference. But this program to tune a satellite dish contributes to a more accurate position estimate.
Features of modern tuners, their settings
Most of those tuners that are on sale are already stitched channels. Therefore, they should not be scanned and sorted. It provides more convenient and simple setup.
For its implementation it is necessary to carry out the connection of the TV and satellite receiver to the electrical network. After you need to turn on the necessary channel on "Astra", because the satellite antenna tuning on the satellite will be carried out in its focus (in other words - in its center).
After that, press the button “Info” on the remote control. When the required channels on the satellite are missing, it is necessary to edit the frequencies of the tangentor. If they are not registered there - you need to do it yourself.When they are driven on scales on the screen, it will be possible to determine the power and quality of the signal.
Some nuances associated with connecting the antenna
In this process there are several important points. For example, you need to properly and well clean the cable. You also need to very carefully carry out the connection of the F-connector, as in the opposite case there may be a short circuit of the braid and the central core. In the worst case, the receiver will deteriorate.
Equally important is the correct connection of the cable to the desired output LNB_IN.
If you connect the entire assembly, you can configure the ports of the disk. But this is a more difficult self-tuning satellite dish.
Satellite setup process
Now the antenna is located approximately correctly and turned to the intended side of the satellite. It is necessary to go into the receiver (tuner) settings and select the corresponding satellite there. After that, you should specify for it the correct indicators of frequency, speed and polarization. For example, for the Sirius satellite, these figures are 11766, 2750 and H, respectively.
Then on the screen you can see two bands. The first will show that the signal is caught by the plate, and the second - the image of its power.When properly installed satellite antenna signal level should be more than 40%. It is only necessary to increase the value of quality, which is at this stage within 0.
If you can not simultaneously adjust the antenna and watch the TV screen, you need to enlist the help of an assistant. He will be engaged in the adjustment of your actions. Then the setup of satellite antennas does not take much time, and will be done fairly quickly and better.
First you need to completely turn the plate on the right side up. From this position it is necessary to slowly turn it to the left and continuously monitor the degree of signal on the TV screen.
If this attempt to capture the signal failed, you need to lower the satellite dish a few millimeters down and repeat all over again.
Setting up satellite antennas is a painstaking search for a signal using manual adjustment.
Setting up the satellite dish "Tricolor" is almost no different from other analogues:
- For its full operation, it is necessary to provide direct visibility to the Eutelsat W4 satellite (36 east).
- Installation works are no different from those for other types of antennas. To provide more accurate signal reception, you must use a satellite receiver of types DRE-4000, DRE-5000.
- The digital terminal is programmed to display exclusively Tricolor TV channels.
- If for some reason manual input is required, then the following signal characteristics must be entered: frequency - 12226 MHz, polarization - left-hand circular, SR - 27.000, FEC - ¾.
Independent antenna connection for receiving "Telecard TV"
Before purchasing a set of "Telekarta TV" in a specialized store, you should decide on what diameter the dish should be. In this case, you must take into account your location relative to the satellite. The indicator of the value of its diameter can vary from 60 to 90 cm.
Configuring satellite antenna "Telekarta TV" is carried out on the satellite Intelsat-15. If it is not in the list of your receiver, you must enter its data yourself:
- converter frequency - 10600
- food - on
Then it is necessary to check the characteristics of the transponder: the frequency should be equal to 12 640 MHz, the symbolic speed indicator - 30,000, FEC - 5/6, the vertical type of polarization and the broadcast format - MPEG2, DVB-S.
After starting the search, the receiver should find 18 channels.There are no HD channels in the TV Card TV package, so when connecting it to more modern TV models, you need to take HD satellite receivers to attention. They convert the satellite signal and "show" a clearer image when receiving "Telecard TV".
"Fit" signal level
In order to fix the position of the antenna, it is necessary that the signal quality indicator be at least 20%. Now you can gently turn it in both directions in order to achieve a minimum of 40%.
But this is far from the end of this painstaking and hard work. In order for the entire system to work correctly, you need 60-80% quality. It can be achieved only by conducting manipulations with the convector. To do this, turn it clockwise or against it until the signal level is satisfactory.
Then you need to adjust the side convectors (if any). It is much easier to adjust the additional heads, since the main one already fully fulfills its functions. It is necessary for each of them to specify the corresponding satellite and catch the signal.This process is similar to that carried out with the main head.
Now it remains a matter of small - this is setting up the channels of the satellite dish and adjusting the TV itself. To do this, you need to streamline all channels - to build them as it will be convenient for each owner. It may be necessary to remove some or block. This process is individual for each user.
