Why is the cauldron antenna signal bad in the last two days?

Due to the wind, shielding or interference, the signal of the small pot will be unstable.

No big deal.

It may be displaced, you can fine-tune the cauldron.

Restore factory settings and search the station again.

Satellite cauldron antennas have three or four unstable signals, what's going on, hello dear, there may be two reasons: 1. There are interference sources nearby, such as electromagnetic interference from high-voltage lines, etc. 2. If the satellite is not accurate, other satellites may be received.

Sometimes, when it rains, even if Lu Yinyu is accurate to the stars, the signal may not be good because of the rain decay. Second, the satellite antenna is often referred to as the cauldron, which is a metal parabola, which is responsible for reflecting the satellite signal into the feed and high-frequency head located at the focal point. The role of a satellite dish is to collect the weak signals from the satellite and remove noise as much as possible.

Most antennas are usually parabolic, but there are also some multifocal antennas that are a combination of spherical and parabolic antennas. The satellite signal is reflected by the parabolic antenna and concentrated to its focal point.

Summary. Kiss! Hello, happy to answer your <>

The signal strength of the pro-satellite antenna cauldron is very good, but the TV does not display the solution, as follows:1、The antenna of the pot lid is not correctly aligned with the star, resulting in the receipt of signal but no signal quality,So there is no sound and no image,You can readjust the elevation angle and azimuth angle of the pot lid,You can observe the actual reception of the TV for fine-tuning and try。 2. The current program channel has been encrypted, and the pot lid cannot receive the signal normally, and it can be switched to other channels for testing.

If you use an irregular receiver, it is easy to have this situation, and you need to change to a genuine receiver to work properly**TV program. Hope mine can help you <>

Do you have any other questions?

The signal strength of the satellite dish cauldron is very good, but the TV does not show it.

But it's good on the ground, but not on the roof, the signal strength and signal quality are very good, but it just doesn't display.
