An antenna adapter (100) for interfacing a portable radiotelephone (200) with external equipment. In a preferred embodiment, a connector assembly (404) includes a first connector portion (406) that inserts directly into the radiotelephone's antenna port, replacing the normal antenna assembly. Matching electrical components (410) on a circuit board (400) are used to match the impedance of the antenna port of the portable radiotelephone. A second connector portion (408) typically uses conventional RF connectors to couple the radiotelephone antenna port to external equipment.
