Description LMR®-400-LLPL-B is the industry standard in high-performance broadband, flexible, low loss 50 OHM coaxial communication cables designed for use in wireless applications. LMR®-400-LLPL-B is an indoor highly fire retardant cable intended specifically for runs within return air handling plenums (e.g. dropped ceilings, raised floors). It has a UL/NEC & CSA rating of 'CMP' and 'FT6' respectively, with fire-code-compliant jacket color. Times Microwave braided coaxial LMR Cables have performance comparable to copper cables, but are non-kinking, extremely flexible and offer easy connector installation. LMR cables are 100% shielded and available in other purpose-specific variations. LMR®-400-LLPL-B can be used in almost any application where handling characteristics, improved shield and low loss is required. Bulk coaxial cable is available as a full spool or cut to length.
