The high-performance HF400 coaxial cable assemblies are 50-ohm, flexible coax cables with RF connectors, manufactured by C&T RF Antennas Inc., and are available in custom lengths from 0.1m to 100m. Used in wireless communication systems and antenna feeders.
The high-performance HF400 coaxial cable is equivalent to LMR400 cable. High-performance, low-loss, ultra-flexible cables in the HF/LMR series use foamed polyethylene as the dielectric material.
These cables feature minimal insertion loss, exceptional flexibility, high frequency capability, excellent abrasion resistance, shielding performance exceeding -90dB, and outstanding cost-effectiveness. They are widely applied in antenna feed systems for mobile communications, base stations, radar systems, and other fields.
HF400/LMR400 represents the next generation of RF coaxial cables, offering enhanced flexibility, ease of installation, and lower costs. These cables are employed as transmission lines in aircraft, satellite, and communication antenna systems. HF/LMR cables are low-loss coaxial cables that deliver particularly superior performance at high frequencies.

Applications include antenna installation, RF test systems, laboratory interconnects, and communication base station feeders. etc.
C&T RF Antennas Inc. offers a wide range of RF antennas, adapters, amplifiers, and cable assemblies. The internal & external antennas with Omni and directional antennas single-band/dual-band/multi-band/extra wideband radio frequencies such as 13.56 MHz, 169 MHz, 230 MHz, 315 MHz, 433 MHz, 868 MHz, 915 MHz, VHF&UHF, ADS-B, 2.4 GHz, 5 GHz, 1.2 GHz, 1.4 GHz, 1.8 GHz, 2G 3G 4G, 5G NR, etc.
