LMR 400 Coaxial Cable
Flexible Low Loss Coaxial Cable
LMR 400 Coax Applications:
- Uses standard connectors (view LMR 400 connectors here)
- LMR 400 coax is designed for jumper assemblies in wireless communications systems or as a drop-in replacement for RG8/9913 air-dielectric type cable.
- These coax cables can be found in short antenna feeder runs.
- LMR 400 coax is suitable for applications that require easily-routed, low loss RF cable (ex. WLL, GPS, LMR, WLAN, WISP, WiMax, SCADA, Mobile Antennas).
- LMR-400-FR carries a MSHA-P rating for mining operations.
- Depending on your type of application, LMR 400 coax cables are available for outdoor, outdoor/watertight, indoor-riser (CMR rated cables) or indoor/outdoor use.

LMR 400 Coax Features & Benefits:
- Flexibility & Bending: LMR 400 coax is designed with a flexible outer conductor, enabling the tightest bend radius of any cable of similar size and performance.
- Low Loss: Lowest loss of any flexible cable; comparable loss to semirigid hard-line cables
- RF Shielding: 50 dB greater than a typical single shielded coax (40 dB) - multi-ply bonded foil outer conductor rated conservatively at 90 dB
- Weatherability: LMR 400 coax is approved for outdoor exposure and is UV resistant. These cables offer a life expectancy of over 20 years.
