RG400 Coaxial Cable

The RG-400 is sold by the foot, with quantities limited to 30 feet. This product is a preferred choice for antenna feedlines in modern aircraft. It provides performance equivalent to the commonly recommended RG-142. While RG-142 features a solid center conductor, the center conductor of RG-400 is stranded and uses a Teflon insulation layer. The outer conductor consists of TWO layers of silver-plated copper braid. This coaxial cable directly replaces the legacy RG-58 product. The PVC and polyethylene materials used on RG-58 are based on WWII-era insulations and are no longer permitted on newly certified aircraft. RG-400 is qualified to MIL-C-17/128-RG400.
