Satellite antenna received quality 0 30

I don't know what kind of machine you use, is it a dual-mode machine? Does your machine have "default settings"? , Is your machine even without a station number or has a station number without an image, and then there are general places where the pot is facing southwest.

First of all, you need to make sure that there is no signal in the position where you put the pot, that is, whether there will be a signal that is not blocked.

A signal strength of 85 indicates that there is no problem with the line connection, and a signal quality of 0 generally means that the satellite is not aligned.

You want to take a look at your ** device frequency (frequency point) Generally, press the F3 key to appear signal detection, if not, press the menu - system settings - password 0000 you can see it Then select the frequency point Find 11880 28800 A group of left-handed, look at the signal strength, if there is a pot again, if there is no signal detection there press the confirmation button, if not, check the line connection. Middle nine is circular polarization, you don't need to care about the polarization angle, just adjust the direction and elevation angle of the pot! If you still can't pick it out, find the group of 12100 28800 right-handed and see if there is one.

If you don't press the exit button to return to the TV interface,It should show that the 001 signal is interrupted。。。 Then put it on**one, and then take the pot to the southwest direction to the star, to see if there will be an image (sometimes the signal quality of the top box is not normal), if there is a call-up, you can. If there is no problem with the high-frequency head, replace it and try it.

First check whether the high-frequency head is broken, then check whether the downlink frequency and symbol rate of the receiving station are correct, and finally look at the approximate direction and elevation angle of the Zhongxing No. 9 antenna installed nearby, and watch the signal quality slowly adjust the direction and elevation angle little by little. Be patient. Complete.

Keep an eye on the signal strength, look for its maximum value, stop when you find it, and try it again if you haven't already! If you haven't already, it may be a factory reset or other setting errors, automatically search for it! It should be able to help you!

Q: 574040705 would love to share their experiences!

First of all, it is necessary to select the right receiving frequency, generally the set-top box of the middle nine press F3 to appear signal detection, if it is not out, press the menu - system settings - password 9999 - then you can see it Then you can see and then select the frequency Select the frequency of 11880.

Signal strength indicates that the line is connected.

The signal quality is what indicates whether the satellite is aligned or not.

I don't know what star you are tuning, first use the star finder software to calculate the polarization angle, azimuth angle and elevation angle of your region and the satellite you want to tune, let the star be tuned first, first adjust the polarization angle (Zhongxing-9 does not need to adjust the polarization angle) in the azimuth and elevation angles.

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, make sail liquid! The reasons for the signal quality of the satellite to be zero are as follows: 1. It may be that the satellite is not aligned, and the direction of the antenna and the angle of the car are adjusted.

2. It may be that the channel has no channel, that is, a station without a program. 3. Processing method: 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% and 55%.

The closer to 55% the fruit is better. If my answer is helpful to you, please give a thumbs up (in the lower left corner of the evaluation of pure things), look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. If you feel that my answer is still satisfactory, you can click on my avatar for one-on-one consultation.

Finally, I wish you good health and a good mood!

Summary. The signal quality of the star antenna is zero, it is not aligned with the star, so there is no signal quality.

The signal quality of the star antenna is zero, it is not aligned with the star, so there is no signal quality.

How to tune. How to tune.

Solution:1The top of the machine destroys the key box to adjust the slim lifter, and the answer is 20 in the alignment of the satellite signal to reach more than 45. 2.Enter the automatic search mode and can receive it automatically.

The quality does not go up. Can't pick it out.

The quality does not go up. Can't pick it out.

According to step one, adjust the ** device and try again.

Connect all the signal cables, turn on the TV and receiver, then you will see the working screen of the satellite receiver, the machine will automatically scan the program, if not, it will prompt that the received program is zero. At this time, press the information button, you will see two stop indications, one is the signal strength (Fu Blind He is about 40% or more), the next one is the signal quality (the indicator bar will become longer after aligning with the satellite, and some will turn green, indicating that the program is locked, and the number is above 30%), at this time, the antenna is aimed at the position of the southwest and slowly moves up and down, while moving to see the change in signal quality strength, if it becomes longer or flashes all of a sudden, then this position is the satellite position, and it is repeatedly adjusted in this position, Until the signal quality is maximum, it will succeed in sleepy.

It's really not possible to find a professional to debug.

Workaround:

The set-top box adjusts the ** device and adjusts it to 20 to align the satellite signal to reach 45 or more.

An antenna is a transducer that transforms a conductive wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Radiocommunications, radio, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, and other engineering systems that use electromagnetic waves to transmit information all rely on antennas to work.

In addition, antennas are also required for non-signal energy radiation to transmit energy with electromagnetic waves. Generally, antennas are reversible, i.e. the same antenna can be used as both a transmitting and receiving antenna. The basic characteristic parameters of the same antenna as transmit or receive are the same.

I wonder if there is a signal strength display?

First of all, you have to check that the receiving system is wired correctly.

After determining the satellite to be received, go to Satellite Parameters** and check the correct receiving parameters.

After setting the program parameters, the antenna triangle is adjusted.

If you are tuning the star, you have to make sure that this set of parameters is correct, and you have to set the correct local oscillator frequency, (depending on the high-frequency head you are using), just adjust it slowly, and you will succeed.

The high-frequency head is broken, try another one.

The satellite angle is not right, which star are you going to receive.

It means that your cable connection is good, but it is not aligned with the satellite, please patiently adjust the direction and elevation angle of the satellite, and the speed is a little slower, because there is a delay. Good luck receiving the show soon.

Follow the steps below to install it;

1 Assemble the lid of the pot, 2 Install the high-frequency head (the F connector of the high-frequency head is down), 3 Connect the receiver and TV.

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

5 After the small pot lid and the receiver are connected, press the F3 button on the remote control (or the star adjustment button), 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 left and right 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, you can produce an image).

6. 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).

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

There is no alignment in the alignment ......The signal strength only means that the machine is connected to the high-frequency head normally! Signal quality is the right signal strength ...... satellite

Have you ever tuned the parameters of your satellite receiver? For example, a 22K switch, is the other one the local oscillator of the high-frequency head tuned? It should be the same as the original oscillator of the high-frequency head on the antenna! If it's all correct, it's not aligning the satellites.

Satellite receiver, commonly known as small pot lid.

The signal of the satellite receiver is difficult to adjust and requires a certain amount of patience.

The signal strength can be received, indicating that the elevation angle of the receiver is roughly aligned.

Fine-tune the angle left and right, adjust it a little and re-collect it until you find the signal quality.

The direction of the receiver is generally south-west, and the elevation angle is about 20 45 degrees, which varies according to each place.

When the signal strength and signal quality are received, the general strength can reach more than 90%, and the signal quality can reach close to 80%, so according to these two values, we can roughly judge whether the satellite receiver is successfully debugged.

If you are not sure about the angle and elevation angle, you can imitate the angle installed by nearby people, and then fine-tune it.

When there is a deviation in the angle, etc., the number of satellite TV signals received will vary greatly.

Your pot may have moved, not for the good star, and then the high-frequency head is broken
