LMR 400-UF UltraFlex Cable
The LMR 400-UF cable is an extremely flexible, low-loss cable designed for outdoor use. It features a bare copper inner conductor and an aluminum tape outer conductor, which enables the tightest bend radius of any cable of similar size and performance. It also has a foam PE dielectric, a tinned copper braid, and a black TPE jacket. This cable has a maximum temperature of 85°C and is rated at 2500V. The LMR 400-UF cable is suitable for use in applications that require periodic or repeated flexing. This cable is compatible with LMR-400 standard connectors. View LMR-400-UF Connectors here.
LMR 400 UF connectors from Times Microwave are suitable for use with LMR 400 UF Coaxial Cable. LMR 400 UF UltraFlex communications coax connectors are available in crimp or clamp attachments and straight plug, reverse polarity and straight jack connector options. Most LMR 400 UF Times Microwave connectors use standard hex crimp sizes.
