Minecom Leaky Feeder
PBE offers the Minecom MCA1000 VHF leaky feeder system providing Full Duplex Voice and Data communications.
The MCA1000 operates in the 150 to 174 MHz frequency range with 2.5MHz of TX bandwidth and 2.5MHz of RX bandwidth.
The system is available as MSHA approved under # 23-A090003-0 for operation in hazardous or explosive mine environments
The Minecom system is flexible for adaptation to any mining or non-mining application.
The down line distribution system is easily changed, expanded, or adapted by the customers' trained electrical staff as the operation grows.
Minecom leaky feeder communication systems are also capable of providing ‘mine-wide’ radio communications in excess of 60 miles of underground mine entries.
In fact, wherever you run Minecom’s leaky feeder cable to our specifications, we guarantee voice and data coverage.
Multiple systems can be networked to cover hundreds of miles or multiple sites.
The Head End can be located either on the surface (required in U.S.
Coal mining) or underground, however it is recommended that the
Head End be centrally located if underground for increased
survivability. The ‘Heart and Brains’ of the system is the ‘Head
End’ (VHE) and along with the voice and data radio repeaters; opional
components such as video distribution units, telephone interface, PBE
Page Phone Coupler, etc.; rack power supply; and stand-by batteries is
mounted in a standard 19” rack cabinet. The Head End supports up to
four leaky feeder output ports for redundancy and economy; a fault in
one leaky feeder leg will have no eﬀect on the other legs. Front panel
switches are provided to enable mine staﬀ to switch the DC power on/
oﬀ to each leaky feeder cable leg to assist with fault ﬁnding and allow
staﬀ to log voltage levels & current drain, etc. Addi%onally the rack
includes a circuit breaker panel with breakers for all major devices
located inside the rack.
