LMR 400 Coaxial Cable
                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.
                The  LMR400 series of cables is a popular low loss flexible RF coaxial cable product group. LMR-400 Flexible Low Loss cables are drop-in replacements for RG-8/9913 Air-dielectric type cable, used as jumper assemblies, for use in short antenna feeder runs, or any application requiring an easily routed low loss cable, such as WLL, GPS, LMR, WLAN, WISP, WiMax, SCADA, Mobile Antennas)


 Features
  • Flexibility and bendability are hallmarks of the cable design. The flexible outer conductor enables the tightest bend radius available
  • Low Loss is another hallmark feature. 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: Designed for outdoor exposure incorporate the best materials for UV resistance and have life expectancy in excess of 20 years.
  • Connectors: A wide variety of connectors are available , including all common interface types, reverse polarity, and a choice of solder or non-solder center pins. Most LMR connectors employ crimp outer attachment using standard hex crimp sizes.
  • Cable Assemblies: All cable types are available as pre-terminated cable assemblies.
