NO AM RECEPTION WITH REPLACEMENT POWER ANTENNA MAST
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 (part
number 22038652) in place of the original RF housing and screw. This is necessary to obtain an RF connection when the lead-in is installed. 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 or open circuit. A check from the lead-in center conductor for continuity to the mast should be "0" ohms.. The RF
pin supplied with the mast and support tube will be too short when used with the original threaded RF cable connector. Using the new RF housing in kit
(part number 22038652) will ensure a good contact. Be sure to use a liberal amount of the grease, supplied in the kit, to prevent water entry (see
illustration).
