RadioLinx® LMR® 400 Cable is flexible with a 1 inch minimum bend radius, LMR® 400 cable can be easily routed into and through tight spaces without kinking. Low loss LMR® 400 has the lowest loss of any RG8/RG13 type cable. This is achieved through the use of a high velocity gas-injected closed cell foam dielectric and bonded aluminium tape outer conductor. Weatherproof the UV protected black polyethylene jacket makes the cable rugged and resistant to the full range of outdoor environments. RF shielding bonded aluminium tape outer conductor is overlapped to provide 100% coverage, resulting in 90 dB RF shielding (180 dB crosstalk) and excellent interference immunity (ingress and egress). Phase stability intimately bonded structure and foam dielectric of LMR® cables provide excellent phase stability over temperature and with bending. The high velocity dielectric results in superior phase stability as compared with solid and air-spaced dielectric cables. Provide the lowest attenuation and are pre-cut and assembled with connectors at the factory to ensure ultimate reliability. Ideal for jumper assemblies in wireless communication systems and antenna feed runs less than one-hundred feet.
