Product Description
The RD-9120 bandwidth adjustable repeater is designed for operation in GSM900 band. Band-specific linear amplifier and filtering effectively amplifies the desired BTS carriers and provides superior out-of-band rejection. Typical units incorporate programmable bandwidth up to 25MHz to suit specific requirements of the network. Remote configuration and surveillance is possible through Comba’s remote control and monitoring system, via PC or wireless modem to the OMT/OMC. Internal Li-ion backup battery ensures alarm signals are sent out during power failure. The RD-9120 comes in an omni-sealed, cast aluminum enclosure, suitable for all weather conditions.
