Abstract
A radiotelephone matching switching system and associated antenna and printed circuit board contact configurations for a retractable antenna employs at least two contacts which are traversely spaced apart in the radiotelephone housing so as to reduce the space used therein. One embodiment also allows reactive components of the circuit to be disconnected thereby increasing the operational bandwidth of the radiotelephone.
