LMR-400-UF UltraFlex
LMR-400-UF is specifically engineered for installations where routing around corners, periodic movement, or repeated flexing is required, all while maintaining excellent RF performance.
Ultra-Flexible Construction: Unlike standard semi-rigid coax cables, the LMR-400-UF uses a stranded copper inner conductor and a robust TPE (Thermoplastic Elastomer) jacket. This allows for a minimum bend radius of just 1.0 inch ( 25 mm).The cable retains the core performance of the LMR-400 family, offering significantly lower attenuation than standard RG-8/RG-213 cables. This means better range and signal strength for your application. Indoor/Outdoor Durability: The TPE jacket is UV-resistant and rated for a wide operating temperature range (typically -40 C to +85 C, ensuring a long service life in harsh outdoor conditions.
