ABSTRACT:
A television (TV) transmission system is adapted to receive a plurality of TV signals and to transmit these TV signals at a plurality of channel frequencies using multi-bay antenna. The system includes a plurality of exciters, each exciter receiving a one of the TV signals and operative to combine the TV signal with a carrier signal at a respective one of the channel frequencies to produce a transmittable signal. Each exciter is coupled to a signal splitter which produces a plurality of split signals from the transmittable signal. A separate power amplifier is coupled to receive each split signal and passes an amplified signal to a power combiner which produces a single combined output signal. A plurality of such power combiners pass their respective output signals to a plurality of antenna elements arranged to radiate as a group.
