RG187A/U 75Ω Miniature High-Temp Coax Taped PTFE Jacket for Defense Aerospace and Industrial Communication Equipment

M17/136-00001 | 75Ω | 1 GHz | 1200 VRMS | -55°C to +250°C

The RG187A/U is a 75Ω miniature high-temperature coaxial cable engineered for specialized VHF/UHF systems that demand extreme thermal endurance, low outgassing, and lightweight construction. With a stranded silver-plated copper clad soft steel inner conductor, an extruded PTFE dielectric, a silver-plated copper braid, and a white taped PTFE jacket, it delivers reliable performance up to 400 MHz in temperatures from -55°C to +250°C. Weighing just 16.2 g/m with a 12.7 mm bend radius, the RG187A/U is ideal for airborne, satellite, and portable radio systems where space and weight are critical. Its white PTFE jacket is low-outgassing and UV-resistant, making it suitable for vacuum environments and long-term outdoor exposure. This is not a broadband microwave cable—it is a rugged, high-reliability 75Ω interconnect for the most demanding thermal and environmental conditions.
