LMR-®400-UF
UltraFlex Communications Coax
Ideal for…
• Drop-in replacement for RG-8/9913 Air-Dielectric type Cable
• Jumper Assemblies in Wireless Communications Systems
• Short Antenna Feeder runs
LMR-400-UF
• Any application that requires periodic/repeated exing
• LMR
®
- UltraFlex has a stranded center conductor
and rubber outer jacket designed for multiple bending/
exing cycles. It is used for both indoor and outdoor
applications.
• Flexibility and bendability are hallmarks of the LMR-
400-UF cable design. The exible outer conductor
enables the tightest bend radius available for any cable of
similar size and performance.
• Low Loss is another hallmark feature of LMR-400-
UF. Size for size LMR has the lowest loss of any exible
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: LMR-400-UF cables are designed
for outdoor exposure and have a life expectancy in excess
of 10 years.
• Connectors: A wide variety of connectors are available
for LMR-400-UF cable, including all common interface
types, reverse polarity, and solder-on center pins. Most
LMR connectors employ crimp outer attachment using
standard hex crimp sizes.
• Cable Assemblies: All LMR-400-UF cable types are
available as pre-terminated cable assemblies. Refer to
the section on FlexTech for further details.
