Why is the satellite weather forecast inaccurate?

1. In case of rain, snow or foggy weather, it can be recovered after the weather improves.

There is water and snow on the pan surface of the satellite antenna.

3. Because of the influence of the sun on the satellite around the vernal equinox and autumnal equinox, it is sometimes impossible to watch it at noon.

4. The antenna is bent or there is an obstacle in front of the antenna.

Satellite program reception clutter is large, and the common reasons are as follows:

1. The receiving antenna is not aimed at the satellite, resulting in a weak signal. We need to adjust left and right to find the best and least cluttered position of the image, and then move up and down to fix it in a cluttered position.

2. The frequency drift of the tuner causes the IF signal to shift, and the amplification factor is greatly reduced. The local oscillation frequency should be adjusted to make the clutter disappear.

3. In heavy rain, heavy snow and foggy weather, the signal (especially Ku band) is attenuated. It returned to normal after the rain and snow.
