leaky feeder systems in chile

Leaky feeder Wikipedia

A leaky feeder is a communications system used in underground mining and other tunnel environments. Manufacturers and cabling professionals use the term "radiating cable" [better source needed] as this implies that the cable is designed to radiate: something that coaxial cable is not generally supposed to do.get price

Leaky Feeders HowStuffWorks

Leaky feeders are different. Instead of covering the cable in a solid copper shield, a leaky feeder has small gaps in the shielding to let the signal through. The gaps create a limited wireless radio network environment. Line ­amplifiers and repeaters boost the signal at regular intervals along the cable to make up for signal loss.get price
