Maintenance problems with satellite dishes How can a satellite dish not be seen

1. If it is to receive 45 sets of domestic TV programs on Zhongxing No. 9. Causes: Weather impact (recovery when the weather gets better) Antenna offset (adjusting the antenna).

2. If you are receiving other satellites, first determine whether some stations will have mosaics Just like putting a disc card, then you need to adjust the antenna, (like the antenna used by Zhongxing 6b now, it is possible that the signal is incomplete, the signal is weak, and the antenna diameter is not large enough) or the quality of the pot is not good enough At the same time, the problem of the high-frequency head or connection line will also cause the signal to deteriorate, and some stations cannot receive it. Another reason is the adjustment of satellite programs, the disappearance of certain channels, or the adjustment of ** device.

It's a good idea to add which satellite you're receiving.

It is best not to have a joint in the middle of the line, and the problem of the line should be eliminated first.

Shaotai has a signal that can't be accepted, or it may be that the station is maintained, and it will be fine after a while, and my family is like this, so I know better, hehe.

It is recommended that you first mark the azimuth and elevation angle of the antenna with a pen, and then fine-tune the elevation angle and azimuth angle, and always pay attention to whether the signal is too coming, if it still can't be called, then transfer it back to the original place according to the mark made, so that even the original signal will be lost.

1. Is there a signal?

2. Is the machine messed up?

3. Check the latest developments on the parameter network to see if there are any changes!

What kind of satellite is your home?

For example, Zhongxing 9 has set up 54 stations, and now there are 45 on it, and the others are empty.

Sometimes some ** devices are affected and have no signal, and when it rains, there will be fewer stations.

Two scenarios. 1.Star program ** business program change.

2.There is a small change in the position of the pot, which causes the signal to become weaker, and some programs with low intensity cannot reach the threshold value and cannot be decoded.

It's also possible that Vanishing Desk was re-encrypted.

Go to the parameter network to check the relevant parameters and see if there are any new changes!

Summary. If you haven't tuned this thing, it's very time-consuming, I used more than six hours to adjust this myself, and it's useless for you to let others tell you how to tune it, because this thing is in the case that you don't know the accurate local latitude and longitude, others can't tell you the exact elevation angle and azimuth angle, so you only have to earn this thing slowly, Zhongxing 6b is generally due south and west.

Is there a card in your set-top box?

There are two reasons for instability: one is that the signal quality fluctuates within 10 points, which is that the signal is not good, not locked, and can be fine-tuned, or the other positive or cluster is the radio and television signal interference, and the signal quality changes more than 10 points. In this way, it is necessary to find the direction of the interference source, block the interference signal with a building or metal, and if the interference signal is in front of the pot, it is necessary to consider blocking the satellite signal when blocking the interference signal.

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.

My friend upstairs is right, and it can be used! If you want to reconnect the method: connect the core wire first, wrap it and then wrap it with a shielding net (both ends should also be connected), and wrap the outermost layer around the adhesive tape!

You can also make do with it, but if it doesn't work, you can buy a line to change it

There are several ways to prevent satellite dishes from being interfered with:

1. Find a location where the interference wave cannot interfere or the interference is small and install an antenna to prevent the satellite antenna from being subjected to scattered interference;

2. Install anti-jamming devices, and install micro-posture hidden wave filters before the satellite signal enters the path to prevent the satellite antenna from being interfered with;

3. Set up barbed wire around the satellite antenna to prevent the satellite antenna from being interfered with and prevent the interference wave from being reflected to the path of the antenna receiving signal;

4. Flip antenna to prevent satellite antenna interference, flip can reduce the height of the antenna, make the effective receiving area of the antenna larger, greatly improve the elevation angle, and enhance the wind resistance;

5. At the outer edge of the antenna perpendicular to the plane of the pot mouth, add a circle of metal strip with a width of 10 to 20cm to prevent the satellite antenna from being interfered with.
