3.16 VHF/800MHz Tx Multi-coupler (50-078015)
3.16.1 Description
The multi-coupler shelf interfaces the VHF/UHF and 800MHz power output signals together to drive
the downlink Tx antennas and to receive the low-level signals from the uplink antennas prior to their
amplification and re-broadcast bask to the BTS.
This purely passive shelf is a mix of hybrid, cross-band and directional couplers which pass the
downlink signals with as little insertion loss as possible and the uplink signals with as good
isolation/rejection as possible. This shelf has no power source and no alarms.
