7/8” RF FEEDER LEAKY CABLE

Norden 7/8" Foam Dielectric Overlapping Copper Foil Leaky Cable is a type of RF coaxial cable which allow the radio signal to leak into or out of the cable along its entire length so the cable functioning as extended antennas. It is suitable for wireless communication in narrow or long, curvy surroundings, such as mining, in buildings, tunnels, subways, high-speed trains, etc.
