These cable assemblies are made from RG-58A/U, Fire-Flex coaxial cable. They are to be used on any single antenna installation, CB, scanner, 2-meter, and 10 meter. Main features of the Fire-Flex coax are:
Stranded center conductor to maximize flexibility and prevent untimely breakage. Shielding coverage that averages 95% to protect against RF leaks and interference. Polyvinyl center insulation for ruggedness and longevity. Performance that exceeds mil-spec requirements for 50 ohm RG-58A/U coax. The mount end termination is the exclusive Fire-Ring. You won’t find a more trouble free, low-profile connection anywhere. All of the coax connections are soldered and protected from the elements. This termination is designed to fit any 1/2″ (13mm) hole. It also has a built in nylon shoulder washer to keep it centered and short free.
