ABSTRACT:
A combined satellite and terrestrial antenna has a reflector dish formed of a conductive metal supported by but electrically insulated from a support structure. A pick-up for the satellite transmission signal is also supported by the support structure at a position to receive satellite microwave signals reflected from the dish. An electrical connector is attached to and in electrical contact with the metal of the dish and a transmission line extends from the connector to transmit UHF/VHF signals which are received by the metal dish itself. The UHF/VHF signals may be combined with the signals from the satellite pick-up and transmitted together on a common transmission line leading to a receiver. A loop section may be connected by swivel connectors to the periphery of the reflector dish to be in electrical contact therewith to further enhance the reception of UHF/VHF frequencies. The loop section may be adjusted to a position either in the front or the back of the dish to maximize reception of UHF/VHF signals.
