RG115 RF Cable M17/92 50 Ohm Double Braid High Power Coax for Aerospace and Defense
Product Description
RG115 M17/92 is a MIL-DTL-17 compliant 50 Ohm high power coaxial cable engineered for demanding RF transmission applications where both power handling and environmental resilience are critical. This heavy-duty transmission line features a 7-strand silver-plated copper conductor and PTFE tape dielectric, delivering exceptional electrical performance through 12.4 GHz. The double silver-plated copper braid provides superior EMI/RFI protection, while the PTFE tape wrapping and fiberglass outer braid jacket offer outstanding mechanical protection and thermal stability. With operating voltage up to 5000V RMS, power handling reaching 2600W, and continuous operation from -55°C to +250°C, RG115 is the preferred choice for high power radar systems, avionics installations, and defense applications where standard coaxial cables cannot meet the power and environmental demands.
