Our LMR-400 is part of our Wire & Cable Line for Coaxial Cables. LMR-400 is made up of a solid bare copper clad aluminum conductor with a Foam Polyethylene (FPE) dielectric, a Polyethylene (PE) jacket, and 2 overall shields of tinned copper braid/aluminum tape. Weighing approximately 68 lbs/MFT, these cables are rated for a voltage of 2500 volts and have a temperature range of -40°C to 85°C. Manufactured by Times Microwave these cables are intended for use in outdoor applications including jumper assemblies in wireless communications systems, short antenna feeder runs and is suitable for applications that require easily-routed, low loss RF cables. They can also be used as a drop-in replacement for RG8/9913 air-dielectric type cable as they are designed with a flexible outer conductor that enables the tightest bend radius of any cable of similar size and performance.
