RG142B/U Bulk Coaxial Cable (by the foot) – $3.70
High-Temperature High-Power Precision RF Coaxial Cable
Engineered for extreme thermal and high-power environments, this 50-Ohm RG142B/U coaxial cable operates from -55°C to +200°C. It features a solid silver-plated copper-clad steel inner conductor, an extruded solid PTFE dielectric, a double silver-plated copper braid shield (95% coverage), and a rugged brown FEP jacket. This low-loss, highly phase-stable cable supports frequencies up to 8 GHz, making it ideal for aerospace avionics, military radar, and high-heat interconnects.
