ABSTRACT:
Direct access to internal radio circuits is provided without requiring additional space on the radio housing to mount a test jack. The threaded aperture (104a) of a bushing (104) is aligned with an aperture (102c) in a radio housing (102). The bushing is attached to the radio housing and the base of an antenna (106) is inserted through the housing aperture and screwed into the bushing, thereby electrically connecting the antenna to the bushing. A printed circuit board (110) is attached to the housing. An electrically conductive spring (112) is held in contact with the bushing and provides an electrical connection between the printed circuit board and the bushing. A test jack (108) is mounted on the printed circuit board and is aligned with the apertures in the housing and bushing. When the antenna is removed, a test plug can be inserted through the apertures in the housing and bushing, and inserted into the jack, thereby providing a direct connection between external test equipment and the internal radio circuitry.
