What causes spin fading of satellite signals?
Pick an answer to check it.
Answer: B. Rotation of the satellite and its antennas
Spin fading is caused by rotation of the satellite and its antennas. As the satellite turns, its antennas point toward and away from you, so the signal rises and falls in a regular pattern. Doppler changes frequency, not strength.
Tip: Spinning satellite, fading signal.
