The Minecom Leaky Feeder System provides a reliable, easily expandable underground communications system that has the ability to expand with your needs.

Why Leaky Feeder?

Radio waves travel by line-of-site, making underground radio communications difficult. Minecom Leaky Feeder solves this problem by forming a long antenna that is installed throughout the mine, providing complete radio communications coverage.  Leaky Feeder cable is strong and flexible, so there is no problem moving the network around corners and turns.

How Leaky Feeder works (see video)

The Minecom Leaky Feeder cable is a type of coaxial cable that ‘leaks’ radio signals, and acts like a long antenna. Amplifiers are installed along the Leaky Feeder cable to boost the signal and compensate for cable loss.  Branch units can be used to send lengths of cable down different pathways.  Minecom’s Leaky Feeder System has the ability to scale and grow with a changing environment in any mine or tunnel.  Each Minecom Leaky Feeder System will be tailored to specific site requirements to provide the best radio coverage.
