Standard Control Station Combiner, 380-450 MHz, 32 Channel

These multi-channel combiners provide frequency-agile operation across their entire frequency range. Control Station Combiners may be used to reduce the number of antennas required on a communications site whilst also ensure that predictable radio-to-radio isolation is maintained at all times – irrespective of individual radio’s Tx or Rx operating mode or antenna isolation characteristics.

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.

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.
