ABSTRACT OF THE DISCLOSURE The connector system includes a radio mounted receptacle with an integral transfer switch, and a separate connector and cable for interface with external radio frequency (R.F.) circuits, and provides a method of connecting external R.F. circuits to a portable radio and for simultaneously and auto- matically transferring the internal radio circuits from an integral radio antenna to the receptacle. The integral transfer switch of the receptacle connector includes a movable conductive plunger retained within a conducting sleeve and adapted to slide in an insulator between a first position at which the head of the plunger engages an inturned end of the sleeve, and a second position in which the plunger engages a flexible contact connected to the radio circuit and moves it away from a contact connected to the self- contained antenna. A connector connected to a coaxial line, which may be connected to external radio frequency signal source, has an outer conductor adapted to connect to the sleeve and an inner conductor which enters the sleeve and engages the plunger to make electrical connection therewith and move the same to the second position. This disconnects the self-contained antenna from the radio circuit and connects the coaxial line thereto. The sleeve, plunger, and inner and outer conductors provide a matched impedance connection from the external source to the radio circuit. The external connector can be manually connected to the radio mounted receptacle connector or automatically coupled thereto when the portable radio is positioned in a carrying housing.
