What is RG58?

Our RG58 Coaxial Cable is ideal for use in CATV and MATV applications. RG58 Coax features a bare copper center conductor, solid low-density polyethylene dielectric, and a black PVC jacket. It also has an overall tinned copper braid shield that helps protect the cable from physical damage. This 53.5-ohm coaxial cable meets the military MIL-C-17 specification, as well as UL AWM 1354 and UL CL2 standards. The Mil-spec version of this coax cable features an M17/183-00001 LS/LT Jacket Type IIA per M17/28-RG58. RG58 cable is ideal for high-frequency signal transmission. It is also suitable for use in antennas and broadcasting equipment.
