RG401 Coax Cable

What Is RG401 Coax Cable?

RG401 is a 50-ohm nominal impedance coaxial cable with good high-frequency power handling capabilities. Originally developed for military communications, RG401 has a silver-coated copper conductor, solid polytetrafluoroethylene dielectric, and a semi-rigid copper tube outer conductor. The cable has a 3,000-volt rating. Main applications include high-frequency signal transmission for wireless communications, radar, and microwave. The cable is similar to the M17/129-RG401 military specification cable and has 18 GHz capabilities. The solid outer tube provides 100% radio frequency shielding.
