FBT^TM is an indoor/outdoor highly fire retardant cable intended specifically for runs within and between base station cabinets. It is also applicable for return air handling plenums (e.g., dropped ceilings, raised floors). It has a UL/NEC rating of ‘CL2P’ for plenum applications.
Flexibility and bendability are hallmarks of the FBT cable design. The flexible outer conductor enables the tightest bend radius available for any cable of similar size and performance.
Low Loss is another hallmark feature of FBT. Size for size LMR has the lowest loss of any flexible cable and comparable loss to semirigid hard-line cables.
RF Shielding is 50 dB greater than typical single shielded coax (40 dB). The multi-ply bonded foil outer conductor is rated conservatively at > 90 dB (i.e. >180 dB between two adjacent cables).
Weatherability: FBT cables designed for outdoor exposure incorporate FEP jackets for UV resistance and have life expectancy in excess of 20 years.
Connectors: A wide variety of connectors are available for FBT-195 cable, including all common interface types, reverse polarity, and a choice of solder or non-solder center pins. Most LMR connectors employ crimp outer attachment using standard hex crimp sizes.
Cable Assemblies – All FBT cable types are available as pre-terminated cable assemblies. Refer the section on FlexTech for further details.
