Middle 9 satellite antenna problem, medium 9 satellite antenna small pot, signal strength 60, qualit

You use a dual-mode machine, that is, it supports the ABS format of Zhongjiu and supports the general DVB format, switching to DVB mode can receive programs from other satellites, but you need a suitable pot and high-frequency head, and you can adjust the angle of the pot, for example, receiving Zhongxing6B requires a cauldron of more than a meter and a C-band high-frequency head of the local oscillator05150. Automatic search may be that it was not turned on during the last upgrade, and if you can't find the program, it should be that the line is not connected, or the position of the pot is moving, you can adjust the signal first, and then search and try.

It must be your friend who cleared the program information to zero.,That's why it will automatically search when it turns on.。 You can factory reset the machine and then switch to the Middle 9 mode. After connecting the line, look at the signal strength first, which should be above 85 under normal circumstances.

If there is no strength or it is very low, there is a problem with the line connection. Dual-mode machine simply means that it can collect large pots and see small pots. There is also a pig in the building who picks the door, and he doesn't give a penny.

Dual-mode is that multiple stars are integrated in a set-top box, it should be the angle to move the wires to connect well, see if there is signal strength, there is proof that your connection is correct, there is no check of the connection line, there is strength in adjusting the quality. You can adjust the signal quality, your machine should be able to receive 46 dual-mode machines are out in the past one or two years, I wish you success.

The dual-mode combination can accept two stars, Medium 9 and Medium 6. Swipe it with a friend's genuine machine. There is a charge for going to the ** business.

The satellite antenna has no signal quality, which means that the satellite is not accurate, and the station cannot be searched at this time; Requires re-staring to be resolved.

The signal strength is more than 60%, indicating that your antenna (pot cover) and the top box at home are in very good contact, and the signal quality is zero, indicating that your angle or direction is wrong or the channel has no signal, that is, there is no program station. Processing method: adjust the direction and angle of the antenna, at least the signal quality should be adjusted to more than 30% before you can watch the program normally, and the signal quality is generally between 25%-55%.

The closer to 55% of the suburban fruits.

The installation of jammers is illegal, you can complain to the local radio administration to report, satellite signal jammers transmit powerful power, not only to satellite signals, mobile phone radios, etc., but also to human health is very harmful, 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.

Report it to your local wireless regulatory board! Or find the source of interference and kill it directly, no one will watch, they are also illegal.

How do you know where the jammer is placed, how do you find it?

The signal strength of 60 proves that your set-top box and the small pot are connected, no quality means that you are not aiming at the satellite, when you are aiming at the satellite quality, the strength will reach more than 90! To tell you a simple debugging method, is to go from the south to the north, every time you look up a little bit and slowly go west, if you don't look up a little bit in the slow turn, that's it!

Copycats? The intensity of 60 has not changed, if it is, it means that the strength is false Check whether the antenna is blocked, whether the line is connected, whether the receiver has adjusted the parameters, and when adjusting the antenna, you must be patient, you must be slow, and the direction is about a little south and west (depending on which city).

If you confirm that the intensity of 60 is correct, it depends on whether the interference is too great.

It may not be a problem with the pot, check the wiring.

If you have tried all the angles, it should be the reason for the high-frequency head or the set-top box, it is best to take your box to someone else's antenna with a small pot to try it, if the box is not a problem, it is a matter of the high-frequency head, according to these years of installation experience, the new high-frequency head can not be used. But I don't know if you're really looking in the right direction.

Still not aligned with the satellite, the nine antenna adjustment method;

1 The receiver and the high-frequency head are connected through a feeder.

2 After the small pot lid and the receiver are connected, press the F3 button on the remote control (or the star adjustment key), the signal strength and signal quality are displayed on the TV, the strength is 60%--70% (this must be there, there is no indication that the feeder is not connected well or the high-frequency head is bad), the signal quality is 0, now you can adjust the pot lid, turn the antenna up and down to find the star, the general orientation is southwest, and look at the signal quality when turning to make it the highest (the general receiver reaches 50% to reach the threshold, and the image can be produced).

3. Fine-tune the lid and high-frequency head to achieve the highest signal quality (70%-80%) (the most important thing is to turn the pot slowly, be patient).

4 Press the exit of the remote control. You can tune in to the show.

Maybe you're not in the right direction!
