NO AM RECEPTION WITH REPLACEMENT POWER ANTENNA MAST
Power Antenna Support Tube Assembly
When replacing a power antenna mast and support tube using the original threaded lead-in (RF cable), it will be necessary to use RF housing kit, P/N
22038652, in place of the original RF housing and screw. This is necessary to obtain a proper RF connection when the lead-in is installed. The RF pin
supplied with the mast and support tube will be too short when used with the original threaded RF housing. Be sure that screws do not contact the mast
inside the support tube when fully seated as this could short circuit the antenna. A check with an ohmmeter from mast to the support tube should show
infinite resistance or open circuit. A check from the lead-in center conductor for continuity to the mast should be "O" ohms. Using the new RF housing in
kit, P/N 22038652, will ensure a good contact. Be sure to use a liberal amount of the grease, supplied in the kit, to prevent water entry. Refer to figure
below.
