Leaky Feeder Cable acts as an antenna to bring wireless voice, data, video and Ethernet into mines and tunnels. When installed in a system using Smart Com 150 and Smart Com 150IS amplifiers, RNG-500 cable will provide a guaranteed 30 m (98 ft) off-cable coverage and 500 m (1640 ft) amplifier spacing. RNG-500 Leaky Feeder cable also provides a flame resistant PVC outer shielding.
