TWIN SAME BAND COMBINER, 1900
Designed to combine two 1900MHz BTS with minimum 5MHz spacing, the Kaelus DBC0097 provides a compact twin combining solution with low insertion. The DBC0097 solution minimizes feeders, TMA’s and antennas thereby saving both capital and operational expenditure when combining two base stations.
FEATURES
- Allows CDMA and LTE base stations to share feeders, TMAs and antennae
- Low downlink and uplink insertion losses
- DC/AISG bypass field settable
- Suitable for indoor and outdoor use
- Down to 5MHz guard band
