ABSTRACT:
In a vehicle mounted radio having a case enclosing antenna trimmer adjustment means with a trimmer adjustment screw accessible through openings in the case and front escutcheon, an insulated tube extends from the trimmer adjustment screw through the case opening. A plurality of electrical contacts within the tube between case and escutcheon have terminal means for connection to active portions of the radio circuitry. A similar contact in the tube within the case has terminal means for connection to the antenna terminal. The tube is effective to receive and guide an adjusting tool to the trimmer adjustment screw or, alternatively, to receive a test probe with a contact adapted to engage the recessed contacts in the tube alternatively by rotation and axial translation through the tube. The antenna contact is shielded from the others by the radio case.
