Why is the signal not good when the ground wave changes?

It is absolutely certain that windy weather has an impact on digital TV signals.

From the way of signal propagation, it can be seen that in the open section, less wind and dust will interfere with the signal, while in the closed section, every cable interface will shake when the wind blows, and the metal interface will also interfere with the signal.

The principle is simple. When the clouds are thick, the good channels of telecommunications are blocked. Just like a person standing in front of an antenna, it will weaken the signal or even have no signal.

Because of the small receiving area, the performance of ku segment is obvious, while that of c segment is slightly less obvious. The weather is bad and the clouds are thick.
