Standard Control station combiner, 746-870 MHz, 32 Channel

RFI’s range of Standard SN Control Station Combiners combine multiple shared Tx output / Rx input (T/R) ports from control station radios and then separate them into two separate paths which can be terminated via a duplexer to a single antenna or connected to separate transmitter and receiver antennas. The CSC provides predictable co-located control station radio transceiver to transceiver isolation and full frequency agility within the designated band.

SKU: CS7486-3205-SN Category:

Compatible with both analog and digital communication systems the CSC is modular in construction providing easy expansion accommodating from 4 up to 32 channels. Fitted to 19 inch rack front panels these units are compact and robust maximizing heat dissipation for relatively high per channel duty cycles.
