Ultra-Flexible Low Loss Communications Coax
• Drop-in replacement for RG-8/9913 Air-Dielectric type Cable
• Jumper Assemblies in Wireless Communications Systems
• Short Antenna Feeder runs
• Any application that requires additional
standard is a UV Resistant
Polyethylene jacketed cable designed for 20-year service outdoor use.
The bending and handling characteristics are significantly better than
air-dielectric and corrugated hard-line cables.
and bendability are hallmarks of
the LMR-400 cable design. The flexible outer conductor enables the
tightest bend radius available for any cable of similar size and
• Low Loss is another
hallmark feature of LMR-400 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).
LMR-400 cables designed for
outdoor exposure incorporate the best materials for UV resistance and have life expectancy in excess of 20
