The Ancor Crimp-On BNC Male Plug is designed to be in conjunction with RG-59 and RG-62 coaxial cable fittings. To install Ancor twist-on connectors, 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 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 connectors for waterproofing and strain relief. Hex: .320/.250.
