LMR-400 Ultimate High-Performance Coaxial Cable
LMR-400 coaxial cable is the industry-leading, high-performance, flexible, low-loss coaxial cable, perfectly engineered as a superior 50 ohm drop-in replacement for bulky and higher-loss cables like RG-8 and RG-213. It strikes the ideal balance between minimal signal loss, physical size, and flexibility, making it the top choice for modern wireless and radio frequency (RF) applications.
Experience up to 50% lower attenuation than traditional RG-8 cables. This is crucial for maintaining signal strength over long runs, especially at high frequencies VHF/UHF and GHz. Despite its performance, LMR-400 maintains a manageable 1 inch minimum bend radius, allowing for easier routing in tight spaces, cable trays, and antenna mast installations compared to semi-rigid cables.
