TWIN SAME BAND COMBINER, 1900
Designed to combine the 1900 A and the 1900 C or E bands 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
- Variable DC / AISG pass options available
- Low downlink and uplink insertion losses
- Suitable for indoor and outdoor use
