How to adjust the satellite dish 15, how to adjust the satellite antenna of the TV?

One is a small pot lid satellite adjuster, which is relatively simple and only needs to be aligned in the direction.

If the signal strength is red, it means that the connection line is normal, and it is best to adjust it to green to indicate that it is aligned with the star.

1.Whether the stability of the pot is good.

2.Whether the elevation angle and azimuth angle are correct, you can adjust and observe at the same time, it is best to put the pot and the TV closer to it, easy to debug, observe the strength of the signal, mainly to adjust the signal quality.

3.See if there is any disturbance in the local area.

The angle adjustment can be ** star finder wizard to calculate the local receiving angle. There should be no shelter in front of the pot. Connect the wire, press the information key, the signal strength and signal quality bar appear, (after the line is connected, the signal strength is about 50 70) first guess the elevation angle, adjust the signal strength to the highest, and then adjust the azimuth, in our country is generally about 30 degrees from the west of the south, from the south to the west slowly turn the pot, the signal quality appears and adjust to the highest, and finally you can turn the high-frequency head a little, adjust the signal to the highest, see if all the stations are closed, fixed on it.

If you can't receive the signal, first check whether there is a problem with the connector of the coaxial cable, if there is a station that can receive it, it means that the antenna is moving. The antenna needs to be adjusted. Before adjusting the antenna, be sure to make a mark in the elevation angle and azimuth, once the adjustment is messed up, it can be restored to the initial state immediately, which can save a lot of trouble.

When adjusting the azimuth and elevation angle, you must be slow, and finally carefully adjust the polarization angle of the high-frequency head to the maximum signal quality, press OK, OK. If adjusting the antenna does not work, it may be that there is a problem with the receiver and the high-frequency head, if possible, you can find a receiver and high-frequency head to replace it.

Generally, according to the adjustment method in the manual, there should be no problem.

A satellite pan is a metal parabola that reflects satellite signals into feeds and high-frequency heads located at the focal point of the satellite antenna. The function of the satellite pot is to collect the weak signals from the satellites and remove the noise as much as possible.

In addition to being parabolic, most satellite pots are also multifocal satellite pots that are a combination of spherical and parabolic surfaces. The satellite signal is concentrated at its focal point after being reflected by the parabolic satellite pan.

Note: Due to policy reasons, except for a few remote rural areas, individuals are not allowed to use satellite pots to receive TV signals.

Satellite pots can be divided into two types: forward feed and partial feed. The forward feed is what we often call the antenna pot, which receives C-band programs, and the partial feed is also called a small pot, which receives KU programs. C-band antennas have

4M and other specifications, in the Northeast region, these specifications can fully meet the needs of receiving all domestic channels and international famous channels such as Phoenix TV, CNN, BBC, NHK. KU antenna, common specifications are .5m, etc., can fully meet the needs of individuals, cable TV spike stations as well"Village-to-village"The needs of the project.

Different from the forward feed antenna, the shape of the partial feed antenna is elliptical, the surface arc is shallow, and the elevation angle is about 20 degrees lower than that of the forward feed when the formal installation is adopted.

1. Put the satellite antenna potato as high as possible, and the hand is in an open place;

First button 2, then turn on the TV, and then determine the direction by rotating the antenna to see if the picture is clear and stable;

3. The satellite antenna should try to avoid the interference of other signals and affect the signal transmission, and should keep a distance from the nearby satellite antenna, if there is a signal interference source from the ground, then use barbed wire or iron sheet to form a signal shielding wall to isolate the connection between the interference source and the satellite antenna. (Be careful not to block the satellite dish from receiving the satellite signal.) ）

1. Place the satellite antenna in a high and open place as much as possible;

2. Then Jane Hao guessed that the TV was turned on, and then the direction was determined by rotating the antenna to see if the picture was clear and stable;

3. The satellite antenna should try to avoid the interference of other signals, affect the signal transmission, and should keep a distance from the nearby satellite antenna, if there is a signal interference source from the ground, then use barbed wire or iron sheet to form a signal shielding wall, blocking the interference source and the satellite antenna of the sock connection. (Be careful not to block the satellite dish from receiving the satellite signal.) ）

Different regions, angles and directions are different. The adjustment degree can be measured according to the following method.

1. Simply understand the principle of satellite TV, there is something (satellite) in the sky that is sending us a signal (radio and television signal), and use this pot in your hand (the outdoor *** receives the signal it sends and transmits it to the TV set at home.

2. First of all, we must know which satellite method to use, there are many ways, I will try to list a few more here for your reference [special circumstances] If you have not moved yet, you can first use a compass (mobile phone ** compass software) to record the direction of the current receiver, and you do not need to understand the satellite information;

3. Turn on the TV, enter the search, program information related settings, see similar satellite names ("Zhongxing 9", "Zhongxing 6b") is, all satellite names can be found on ** (Chinese Star Finder Network); Check the original program parameters on the TV (find a random TV program), compare with the program parameters on the Chinese Star Finder Network, which star has the same parameters as that star, as shown in the figure below "Satellite Parameters of "Hunan Satellite TV";

4. Call ** to ask for after-sales, people don't give free transfer, ask which satellite is not good? What I have learned is that the following two are generally used in rural areas today:

Zhongxing 6b ("cauldron").

Zhongxing No. 9 (Huhutong, "small pot").

According to this rule, the big pot first tries Zhongxing 6b, and the small pot first tries Zhongxing 9.

5. The longitude of the satellite can also be queried on the Chinese satellite search network. Since they are geostationary satellites, they are all at the equator, so the latitude is 0. There is no need to check the two commonly used satellites: Zhongxing 6b: Zhongxing 9:

6. Understand the azimuth and elevation (or downward inclination) This is equivalent to looking at the moon in the sky, if the moon is behind you, you need to turn around (adjust the azimuth), and then look up (adjust the elevation angle) and then put on two professional pictures.

<>7. As long as we use the "Satellite Director" to select the satellite to be located, it can correct the direction (adjust the azimuth) for us in real time; For the elevation angle, I personally feel that it is not necessary to calculate so accurately in actual operation, first adjust the azimuth angle, and slowly adjust it up and down on the basis of a roughly 45-degree angle.

8. Adjust the azimuth angle of the mobile phone to turn on the satellite director, enter the state of real-time correction to ensure that the direction of the mobile phone is consistent with the reflective surface of the first place, there are two recommended practices: first, the mobile phone is close to the device (high-frequency head) connected to the middle of the pot; Second, the phone is placed directly below the pot;

<>9. Adjust the azimuth angle and adjust the elevation angle slowly. Test open the TV and set-top box to see if you can broadcast TV programs.
