Flexible Low Loss Coaxial Cable
Times LMR 400 Coax Applications:
- LMR-400 coax cable uses standard connectors (view LMR 400 coax connectors here).
- LMR 400 cable 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.

Times Microwave 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: LMR 400 coax cable features the lowest loss of any flexible cable, comparable to the loss of 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: Approved for outdoor exposure and is UV resistant. LMR 400 cables offer a life expectancy of over 20 years.
