Satellite dishes, there is a signal but no quality, what is the matter?

Signal strength indicates that there is a satellite field strength locally and that it is wired correctly. The signal quality is high, the picture is smooth, and there is no quality to indicate that the satellite is not right.

Here's how to adjust it:

In addition to adjusting the left and right directions, the up and down elevation angles of the cauldron; It is also necessary to adjust the direction and focal length of the high-frequency head; See if the pot is a standard parabola, that is, whether it is deformed; There are no conductive obstacles ahead; Whether the receiver is good or not, try to change friends to know! Whether the high-frequency head is good or not, if there is no problem and the line connection is correct, it can be determined that the high-frequency head is broken;

Then you can also automatically search for it, and press the information button to see if there is signal strength when adjusting, and if not, it means that the antenna has not been connected; Only when the signal strength is more than 70 means that the antenna is connected, and then the signal quality is adjusted to more than 40 to see, of course, the higher the signal quality, the better.

I don't know if you're a friend.,If I'm near us, I'll go directly to your house to tune it for you.,I won't be really anxious when I buy an antenna.,We have a small pot here that is aimed at the southwest direction.,About 3 o'clock in the afternoon when the sun is in that place,You're **,There are specific parameters on the manual,(There can be no obstacles in the southwest direction, such as trees and buildings) elevation angle, you see the TV signal quality comes out, and then the elevation angle of the pot lid is ** to the maximum (my small pot signal quality reaches 50) Viewing is normal, If you are reluctant to spend money, who has it near you, let him get it for you, you can also consult the way to buy it, I wish you good luck, Happy New Year!

Aim the pot in the southwest direction and slowly adjust the adjustment, don't be in a hurry.

The hand should move slowly, and the joy of moving cannot be adjusted.

It means that your pot is not aligned

The direction of middle 9 is in the southwest direction, don't always adjust left and right, up and down, it's very simple, you try, be patient.

There is no mass, strength 85, progress lo0

If there is no signal quality, it means that the satellite pot is not aligned, and you need to fine-tune the satellite pot and high-frequency head up and down, left and right.

The satellite pot is what we often call an antenna, which is a metal parabola that is responsible for reflecting satellite signals into the feed and high-frequency head 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.

Most satellite pans are usually parabolic, but there are also some multifocal satellite pans 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.

There is strength, which means that the connection is good, but the satellite pot is not right, so there will be a situation of strength but no quality.

Solution: Before adjusting the satellite, you must first know the azimuth, elevation, and polarization angles of Zhongjiu in your area, and it is very important to find the satellite with three points and two in one.

Most of China's cities are south-west, and then the machines and TVs are connected, and a station is set up in the machine, if the normal connection machine has satellite strength, the quality is not, and if there is, it is between four and five.

Then slowly turn the pot to see if there is any change in signal quality, and the program can generally be received by about 30. It is limited by a machine door. If there is still no moving elevation angle, it is also raised and lowered in the circle, and the pot is slowly turned to see if there is any change in signal quality, if the signal quality.

The amount can only reach The program is there and there is a mosaic, that can slowly turn the high-frequency head, and the signal quality will be higher. Note that the pot should be slow, the signal strength is connected to the high-frequency head of the machine, there is no way to say that it is not connected, and the signal quality is the bigger the better, not the strength.

The satellite dish has a signal strength of more than 90 and a quality of zero, what's going on!

The signal strength of the satellite antenna is more than 90, the quality is zero, and if the machine is troubleshooting, the most likely thing is that it is interfered with by the cable TV department. Countermeasure 1: Find the shielding position, the satellite signal is from the sky, the wired interference signal is transmitted from the ground, and the signal transmission angle between them is 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 judge 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 of 1 4, that is, <.

This is the easiest to buy some metal mesh in the hardware store But if you get too much to block the signal, don't blame me 3, choose a short-throw antenna commonly used forward feed antenna focal length aperture than f d in the middle (note: f represents the focal length of the antenna parabola, d represents the antenna mouth diameter), f d >, belongs to the telephoto antenna, the feed installed at the focal point is located outside the antenna mouth, which is characterized by a long focal length and high signal gain, but poor anti-microwave interference. We can use a short-throw antenna, which has a < of fd, because the feed is between the antenna mouth surface and the reflective surface, the focal length is short, the anti-interference is good, but the signal gain is slightly poor.

4. The above measures cannot be solved by using the above measures in the interference area, if the signal to be received can also be received on the C-band of other satellites, it can be received by the satellite. By changing the direction of the receiving antenna, you can see if you can avoid the interference area of the interference wave, and you can also relay the Ku-band signal on the satellite to avoid interference. 5. Set up a power dissipation unit to set up a plurality of power dissipation units in the area near the transmitting antenna of the satellite signal jammer to weaken the interference effect.

The power-consuming unit can be wound into a hollow coil with coarse enameled wire (more than ten turns), and the two ends of the coil are connected to a small bulb or light-emitting tube for flashlight.

Hello dear! The satellite canapon has no signal strength and signal quality, but the reasons are as follows: the main reason is that the angle is wrong, and the signal strength is the connection between the receiver and the F head of the satellite pot, which can generally reach about 97%.

Signal quality is a data indicator of whether the satellite pot is accurate to the satellite. It is necessary to carefully adjust the angle of the satellite pot to the traveling star. Workaround:

Use the TV guide channel to find the stars (parameter 4060 vertical 27500), the high-frequency head is aimed at the center of the pot, and the high-frequency head is zero scale horizontal. Press the information button, the signal strength and signal quality information bar appears, first adjust the elevation angle, adjust the signal strength to the highest, and then adjust the azimuth and regret the pin angle, (generally due south slightly east or west, which is related to your local longitude), the signal quality appears, and adjust to the highest, and then change to Hunan and Sichuan and other stations with weak signals, and adjust the signal to the highest, (at this time, you can fine-tune the polarization angle, azimuth angle and elevation angle until the station is fully closed). Hope it helps!

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.
