Abstract

A portable radiotelephone includes a chassis and antenna connector with an impedance of less than 200 ohms, the antenna connector supporting an extendable antenna that is movable back and forth between extended and retracted positions relative to the chassis. The antenna connector also can support a fixed antenna or a connection to external equipment. A universal radiotelephone housing includes a single external connector port for selectively providing electrical connection to both an extendable antenna and external test equipment, precluding the need for separate test and extendable antenna ports. The single external connector port includes an aperture allowing the extendable antenna to pass therethrough.
