50 Radiating Coaxial Cable

Antenna Factory 50 ohms radiating coaxial cable is mainly used in tunnels, mines, subways, high buildings and highways where there is no direct or good radio wave as signal transmission and transmitting and receiving antennas duplex functions. The cable is characterized with low attenuation, low VSWR, high power capacity, good signal coupling and corrosion resistance.

The cable is manufactured on argon arc welding, corrugating and slotting production line with the most advanced technology by slotting the holes along outer conductor axis. So the evenly-distributed relatively strong radiating signal in the close vicinity of the cable along ts axis make it possible signal transmission, across long distance in uncovered ared.
