TWIN SAME BAND COMBINER, 1900

Designed to combine two sub-bands within the1900 band, the Kaelus DBC0081 provides a compact twin combining solution with low insertion, The DBC0081 solution minimizes feeders, TMA’s and antennas thereby saving both capital and operational expenditure when combining two base stations.

FEATURES

  • Allows two 1900 base stations to share feeders, TMAs and antennae
  • Field selectable DC/AISG bypass with built-in lightening protection
  • Low downlink and uplink insertion losses
  • Suitable for indoor and outdoor use
