Abstract
A satellite TV receiver for receiving a satellite broadcasting, wherein neighboring televison signals are vertical and horizontal polarized waves, and wherein a polarizer for the satellite receiver controls an antenna so that the polarization plane of the antenna is adapted to the polarization plane of television signal to be received. The receiver further includes a narrow band-pass filter for rejecting terrestrial interference so that the desired polarization plane can be more easily determined.
