About RG142
RG-142 is a double-shielded 50-ohm PTFE coaxial cable rated for operation from cryogenic temperatures up to +200°C with a 0.195" outer diameter. Its dual-shield construction provides excellent EMI rejection while the PTFE dielectric ensures stable electrical performance across a wide frequency range. The preferred choice for military, aerospace, and high-power RF applications.
