LMR-300-75

LMR 300-75 Ohm

The LMR 300-75 ohm coaxial cable is a flexible, low-loss cable manufactured by Harbour Industries. This cable features a bare copper inner conductor and an aluminum tape outer conductor. This outer conductor 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 PE jacket. The LMR 300-75 Ohm is UV resistant, is suitable for outdoor exposure, and has the lowest loss of any comparable flexible cable.
