Ask for help with the problem of the satellite dish, how to debug the satellite dish

The satellite dish is not properly adjusted. Since the place has changed. The azimuth of the antenna has changed.

Whether the new place is flat, if not, adjust the elevation angle. Choose a station first. Press the Info key.

Adjust the azimuth angle left and right to see if there is any change in signal quality. If there is a holiday, adjust it to the maximum value. Adjust the elevation angle again to the maximum.

Generally, you can watch it normally. If the adjustment is not good, adjust it according to the method I said. Here's how I adjusted the satellite receiver antenna for your reference::

After connecting the machine, press the information button, at this time, only the signal strength is more than 70%, and the signal quality is zero or very small, indicating that the connection is correct. It's just that the azimuth and elevation angles are not adjusted well. Use the star guide to determine and estimate the azimuth and elevation angles of the received satellite.

First find a satellite program with a strong signal (the program parameters of several satellites are stored in the machine when leaving the factory), such as Beijing Satellite TV with a strong signal here. Hunan Satellite TV also has a strong signal. Press the information button, and the Asian 3s azimuth is in the southwest direction.

First, determine the approximate position of the antenna azimuth. Then adjust the elevation angle, the elevation angle is not fixed at first, repeatedly adjust the elevation angle size, after each elevation angle, rotate the azimuth angle, and see if the signal quality has changed, as long as there is a small change to capture the satellite signal, and then carefully adjust the azimuth angle and elevation angle, when the signal quality reaches more than 30 percent, you can watch the program. Finally, it is necessary to adjust the polarization angle of the lower high-frequency head and the focal length of the high-frequency head.

The polarization angle is equal to the satellite diameter minus the local diameter. The zero degree of the high-frequency head is in the horizontal position. As long as you adjust carefully, you will be in the best condition.

A lot... Check on the Internet, there is one diagonally opposite the north gate of the century.

Installation and commissioning of satellite antennas (taking Nanxing debugging as an example):

1. Assemble the lid and fix the high-frequency head.

Third, the installation of the pot lid:

1. Formal wear. Formal installation is the easiest way to install, but the conditions must be met and there is a flat place. In general, rural housing is used in this way.

2. Upside down. For urban buildings, if there is a protective net on the window, it will not work with formal wear, and it is easy to install it upside down and firm.

It will not be a problem to fix it with iron wire for several years, for some high-frequency heads that are easy to enter the water, when installing, remove the front plastic cover, or make a big hole, and it is not good to be small.

4. Adjust the angle and orientation of the antenna.

Press the remote control information button twice, the signal strength and quality appear on the screen, when the quality reaches about 70%, the signal is basically adjusted, and the antenna must be fixed at this time. In order to avoid wind blowing and shaking, the signal will be unstable. As shown in the figure below.

At this point, the satellite dish is adjusted to watch TV.

1.Equipment: Antenna (pan) side. High-frequency head one. Several signal lines. One receiver.

2.Installation and commissioning: First connect all the devices.

Turn on the TV and receiver. (If there is a satellite program you want to watch in the receiver, you can save a short) and find the parameters of the satellite you are watching. Then press the menu of the receiver remote control - program settings - modify program parameters - change the program parameters to the parameters you found on the Internet.

Just change to the downside. Polarization and symbols. The rest does not move) - save - press the info key again.

You can see the information sheet. These are the parameters you just modified. None of that.

Looking at the signal strength and quality below, the strength is generally above 60. The quality is lucky, and you can put it on. If it's bad, it's 0.

The next step is star hunting. (The direction of the 3S is about 25° west-south.) Zhongxing-6b is about 15° west-south.

Xin San is around 5°. The rest can be determined by looking at the latitude and longitude of the satellite. The smaller the more westward.

The larger the more eastward) the general direction is determined that is, the elevation angle, and the middle 6 is about 20 ° from the horizon. The polarization angle is not easy to calculate. Slowly turn the high-frequency head to debug.

Watching TV while adjusting three angles. Until signal quality appears. After the signal quality appears, it's time for fine-tuning.

Maximize signal quality. That's it. The next step is to search the station.,If the receiver has a blind scanning (automatic search) function, it will search the station directly.。。

If you have it, you can add the program manually. Menu - Program Settings - Add Program - Input Parameters (Down. Symbol.

polarization of these three) to confirm it. After searching all the stations, delete the encrypted program and you're done.

Hello, did the answer help you? If you have any other questions, please consult me within 24 hours, and if it helps you, please give me a thumbs up, thank you.

Answer to see if the signal quality is poor and sometimes the signal can't be locked? If the line is fine, see if the line interface is virtually connected, if not, you can only fine-tune the pot. Turn the signal quality to the highest and fix it. Rain will also affect the signal, and it will be fine after a sunny day.

You first see what the signal quality is, press the F3 key word (star) key with the small pot remote control, at least reach more than 50 Note that it is not the strength to get it bad, you can play**.

If you don't get the question right, your ** should add the area code.

First of all, connect the wires! It's best to move the TV out there, which star are you going to receive! For example, the star six b will be selected to the star program,Generally stored on the machine,If there is none,Select the increase **device,Enter one of the set of parameters (parameter online search) local oscillator frequency selection5150,Then slowly adjust the pot to the TV to make the signal quality the strongest!

Signal strength 74 signal quality 1, indicating that you are not aiming at the satellite, which satellite signal you are receiving, and then check the elevation angle and azimuth angle of the satellite you are at your location to receive, as well as the polarization angle, and there will be an image. If you still don't understand, you can add me 305883727.

It is illegal to install jammers, and you can file a complaint with the local radio administration or directly with the Ministry of Industry and Information Technology.

Satellite signal jammers transmit powerful power, not only to satellite signals, but also to mobile phone radios, and are very harmful to human health, especially children and pregnant women. You can eliminate interference by yourself before removing the jammer: satellite TV signal jammer precautions 1. Find the shielding position Satellite signals come down from the sky, wired interference signals are emitted from the ground, and the signal emission angles between them are different.

It can find the position where the interference wave cannot interfere or the interference is small, that is, the interference dead angle. Interference waves and satellite waves are both straight line waves, which will be reflected when encountering obstacles on the way, but the difference between these two types of radio waves is that the field of interference waves is tens of millions of times stronger than satellite waves, resulting in reflections in all directions after encountering obstacles and buildings, while satellite waves are easily absorbed by the surface if they are not reflected by antennas. The easiest way to find a shield location is to lower the antenna height, as jammers have a certain height when transmitting microwave interference signals.

Secondly, the surrounding natural objects can be used to avoid the surrounding strong microwave interference signals, such as placing on the open ground is better than placing it on the top of the floor; The antenna can also be moved to the other side of the building, which can be used to block interference waves from that direction. 2. Install an anti-jamming device to determine the best direction of the interference wave, and set up a metal mesh on one or more sides of the antenna to block the interference wave and reflect the interference wave. The height of the metal mesh should exceed the high-frequency head on the satellite antenna, and it should not block the travel path of the satellite signal.

Since the wavelength of the C-band signal is in between, if the metal mesh is used to shield the interference wave, in order to prevent the interference wave from leaking into the metal mesh, the mesh aperture should be less than the shortest wavelength 1 4. i.e. small. If the interference is not too serious, you can also add a metal strip with a width of 10 20cm on the outer edge of the antenna, perpendicular to the plane of the pot mouth.

Of course, the wider the width of the metal band, the stronger the anti-interference performance, but the antenna of one pot and multiple satellites should not use this method, it will block the satellite signal reception that is not perpendicular to the surface of the pot.

1 Lower the position of the lid and block the interference signal through the building.

2. Block by installing an anti-jamming net
