Broadband Short-Haul Control Station Combiner, 40-960 MHz, 8 Channels

These multi-channel combiners provide frequency-agile operation across their entire frequency range. Short-Haul Control Station Combiners may be used to reduce the number of antennas required on a communications site whilst also ensuring 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 Broad Band Short Haul Control Station Combiners address the need to combine multiple shared Tx output / Rx input (T/R) ports onto a single feeder line or suitable antenna. The BB SH CSC provides predictable co-located control station radio transceiver to transceiver isolation and full frequency agility. Compatible with both analog and digital communication systems the BB SH CSC is modular in construction providing easy expansion accommodating from 4 up to 32 channels.

Mountable into a 19 inch rack frame or cabinet these units are compact and robust maximizing heat dissipation for relatively high per channel duty cycles. The BB SH CSC is typically used where the distance between the control station and base site/repeater is less than 5km.
