Abstract
A broadcast receiving system for use with an FM radio transmitter in a vehicle includes an adapter unit and an antenna unit. The adapter unit includes a connector to a vehicle's existing power system, e.g., cigarette lighter receptacle. The adapter unit receives audio program signals from the antenna unit, and retransmits them to a vacant FM channel or to an intermediate frequency channel of the vehicle's FM radio receiver. The antenna unit receives radio broadcast signals having frequencies in the range of about 300 MHZ to about 4000 MHz from satellites and terrestrial repeaters.
