A polarity switch for connection between a dual antenna system and a satellite television receiver to permit multiple receivers to simultaneously receive channels of different polarity includes a pin diode switch and input circuitry to decode the standard receiver signal previously used to rotate the antenna feed of a single feed antenna.

Polarity switch for satellite television receiver

An electronic switching circuit for providing solid state switching of a plurality of incoming radio frequency information channels, with the circuit providing a pulse processor for altering the timing of the incoming channels, comparator/integrator circuitry for redefining the pulse width of the incoming channels with reference to a standard voltage level, level translator circuitry for further redefining the input channel level, and radio frequency selection gates for error-free discrimination and selection among the incoming channels.
