LMR195  Cable Assemblies

Flexible Low Loss Communications Coax LMR-195

Ideal for...

  • Jumper Assemblies in Wireless Communications Systems
  • Short Antenna Feeder runs
  • Any application (e.g. WLL, GPS, LMR, WLAN, WISP, WiMax, SCADA, Mobile Antennas) requiring an easily routed, low loss RF cable
  • Drop-in replacement for RG-58 and RG-142
  • Low Loss is another hallmark feature of LMR-195. 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-195 cables 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 for LMR-195 cable, including all common interface types, reverse polarity, and a choice of solder or nonsolder center pins. Most LMR connectors employ crimp outer attachment using standard hex crimp sizes.
  • Cable Assemblies: All LMR-195 cable types
