Does rain affect the signal..? Why..?
Yes, heavy rain may affect your signal. This phenomenon is known as Rain fade can occur due to weather at reception of signal or at the source causing rain fade. This is unfortunately a feature on all satellite systems worldwide.
Rain fade affects the signal in 2 key ways.
Firstly, satellite signals become weaker as they pass through raindrops. This is a law of physics, that is, regrettably, beyond our control and which no satellite company in the world has been able to get around.
Secondly, the location of the storm is important. Even though the storm may not be in your area, storms in other locations (basically, any place where our signals originate and transmit to and from) can still affect your signal
