LMR-400-UF

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 flexibility

LMR 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.

Flexibility 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 performance.

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).

Weatherability: LMR-400 cables designed for outdoor exposure incorporate the best materials for UV resistance and have life expectancy in excess of 20 years.

Connectors: THESE JUMPERS wired with hand soldered Amphenol PL-259.
