Abstract
A radio transceiver of the present invention includes a transmission line within a housing. The transmission line is comprised of a hollow center conductor and an outer conductor, both connected to a transceiver circuit. The transmission line is also connected to a low impedance connector which is coupled to the housing. A retractable 1/2 wave antenna having an integral matching section will be matched to a transceiver circuit when extended. When the antenna is retracted, the antenna is retracted within the center conductor and acts as a 1/4 wave antenna and will still be matched to the transceiver circuit.
