Satellite radio signals are not affected by rain and weather.
Satellite TV Providers transmits the signals through their satellite dish converting it first from digital signals to analog signals. These signals which were converted will be transmitted to the satellite. The satellite will then transmit the analog signals per request of the satellite dish connected to the receiver of the subscriber. Once signals are received, it will be converted back to digital signals which can be read by the receiver and be displayed to the television.
Satellites receive signals from Earth using antennas that are pointed towards the ground. The signals are sent from ground stations and relayed to the satellite. The satellite then processes the signal and can transmit it back to Earth or to another satellite.
