Flexible Low Loss 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
  • Any application that requires periodic/repeated flexing

LMR-400 Ultraflex coaxial cable provides excellent performance for high power HF needs or VHF/UHF applications. Note that it has a stranded center conductor to greatly improve flexibility. This cable combines superior performance with good flexibility.

LMRŽ- UltraFlex has a stranded center conductor and rubber outer jacket designed for multiple bending/ flexing cycles. It is used for both indoor and outdoor applications.

Flexibility and bendability are hallmarks of the LMR- 400-UF 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- UF. 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-UF cables are designed for outdoor exposure and have a life expectancy in excess of 10 years.
