RG142 MIL-DTL-17 Compliant Coaxial Cables 4.95mm 8GHz Feeder Cable with FEP Jacket
RG142 is a MIL-DTL-17 qualified 50 Ohm coaxial cable (M17/60-RG142) engineered for high-frequency applications up to 5 GHz. Featuring a solid silver-plated copper-covered steel center conductor and double silver-plated copper braid shields, this cable delivers exceptional shielding effectiveness and stable electrical performance across a wide temperature range from -55°C to +200°C. The 4.95mm diameter FEP jacket makes it a popular high-temp drop-in replacement for RG58 applications.
