SMART COM 150 HEAD END
SMART COM 150 HEAD END
RNG-H12, RNG-H36

Varis’ Smart Com 150 Head End (HE) is the interface between Base Station equipment such as
Repeaters and the Smart Com 150/150IS Leaky Feeder network. Head End units have a pre-amplifier which
compensates for the splitting losses in the Head End and performs system Automatic Gain Control (AGC).
The Head End unit also injects DC power onto the Leaky Feeder cable to power Smart Com 150 Line amplifiers
located near the basestation.
