ABSTRACT:
Converter apparatus for interconnecting a universal replacement power antenna to the original equipment components of a vehicle radio system or the like, and for automatically steering the electrical control signals to maintain the proper up-down operating function. The connector apparatus comprises an electronic converter module, a group of wire terminal connectors and a connector block, the latter consisting of a three lead, polarized female connector, compatible with an existing connector in the vehicle system. A pair of diodes are used in the electronic converter module to automatically steer control signals among three interconnecting wires between the original equipment antenna relay and the replacement antenna relay.
