RG402 Coax Cable M17/130 50 Ohm .141 Semi-Rigid Copper Tube Coax for Microwave Application

RG402 M17/130 is a MIL-DTL-17 qualified 50 Ohm semi-rigid coaxial cable engineered for microwave and millimeter-wave applications demanding absolute signal integrity. Unlike flexible braided cables, this precision transmission line features a solid copper tube outer conductor that provides 100% RF shielding and maintains precise spacing between center conductor and dielectric. The result is exceptional impedance control, phase stability, and the lowest possible insertion loss through 20 GHz. With shielding effectiveness exceeding 110 dB, RG402 effectively eliminates electromagnetic interference in sensitive receiver systems and test environments. The PTFE dielectric and silver-plated copper-clad steel center conductor deliver consistent performance across -55°C to +150°C, making it the go-to choice for radar systems, satellite communications, and precision laboratory measurements where cable-induced phase error cannot be tolerated.
