RFS Technologies 2HB12-50JPLR is DragonSkin 1/2 in. fire-resistant standalone coaxial cable, certified to UL 2196 for 2-hour circuit integrity. It keeps cellular and public safety radio communications working to and from all floors of a burning building, meeting NFPA 72 and NFPA 1221 survivability without conduit or cable wrapping.
The cable has solid inner and outer conductors, which virtually eliminate intermodulation, a red plenum-rated jacket, and uses standard RFS connectors and installation techniques. It is made in the USA.
