The Ancor Coax Bulkhead/Deck Feed-Through is designed to be used in conjunction with PL-258 coaxial cable fittings. To install this twist-on connector, strip the cable to expose 9/16" of the center conductor. Strip the outer jacket to expose 1/4" of the braid. Make sure that the braided shield does not touch the inner conductor. Insert the cable into the connector until the center conductor protrudes through the center of the connector. Twist the small knurled end while gently pushing the connector onto the cable until resistance is felt. Crimp or solder the center conductor, and cut off any excess. It is strongly recommended that a piece of Ancor 3/4" heat shrink be installed on all exterior UHF connector to waterproof the connection and relieve strain. Fitting: 1/8" with nut.
