Mobile Signal Booster
7/8" Leaky Cable is a type of RF coaxial cable which has gaps or slots in its outer conductor to 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.
