Mine Radio Underground Communications: Leaky Feeder Radio System
 |
Raveon’s M7 series radios are well-suited for underground mine radio data communications. With the fastest Transmit / Receive turn around time in the VHF/UHF radio modem business, your polled telemetry system will operate fast and efficient within an underground data system using a pair of cables one of which is a radiating cable the other a “receiving cable”. – a setup commonly referred to as a “leaky feeder system“. “Radiating Cable” implies that the cable is designed to radiate or asborb RF signals: something that coaxial cable is not generally supposed to do.
A leaky feeder system is used for underground mining or tunnel environments where line-of-sight radio communication is difficult or impossible to achieve. Radios are connected with a coaxial cable with a receiver (Rx) port on one end and a transmitter port (Tx) on the other side of the radio. |
