Control Station Combiner

Control Station Combiner

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 while also ensuring that pre-dictable radio-to-radio isolation is maintained at all times - irrespective of individual radio’s Tx or Rx operating mode or antenna isolation characteristics.


Short-Haul Control Station Combiners provide fixed isolation between radio units using power attenuators and signal-combining techniques. The result is a constant isolation between radios regardless of the frequencies. Additionally, the higher per channel insertion losses resulted from the use of attenuators protect the receivers at the base site and the Control Stations from being overloaded by the transmitters in close proximity. These capabilities can significantly reduce tower clutter and loading, and simplify cabling installation at Control Center facilities.

Because these Short-Haul Control Station Combiners are specifically designed with higher insertion losses for applications where the control stations and the base sites are less than 5 miles away, careful link budget analysis need to be conducted to verify signal strength and availability before the selection of these Short-Haul models. Regular Control Station Combiners with significantly less insertion loss are available for normal applications.”


Models are available in the 132-174 MHz, 380-520 MHz and 746-960 MHz bands, in standard configurations of 4, 8, 16, 24 and 32 channel capacities. Other frequency bands and higher channel capacities are also available upon request..
