FBTTM-400
Flexible Low Loss High Power Communications Coax
　

Ideal for…
• High Power Base Station Jumper Assemblies
• In-Building Plenum Feeder Runs
• Any High Power Low Loss RF cable application
FBT-400 Indoor/Outdoor FEP Brown 54171
• FBTTM 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-
400 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-400.
Size for size FBT 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-400 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-400 cable, including all common interface types,
reverse polarity, and a choice of solder or non-solder
center pins. Most FBT connectors employ crimp outer
attachment using standard hex crimp sizes.
• Cable Assemblies – All FBT-400 cable types are
available as pre-terminated cable assemblies. Refer
