Standard Control Station Combiner, 150-174MHz, 4 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.
Single antenna-port mobiles may be connected to these combiners to provide operation on two-antenna configurations (one Tx and one Rx), or through a duplexer to a single antenna (i.e. Tx/Rx). These capabilities can significantly reduce tower clutter and loading, and simplify cabling installation at Control Center facilities.
Models are available in the 380-450MHz, 400-470MHz and 450-520MHz bands in standard configurations for 4, 8, 12, 16, and 32 capacities. Other frequency bands and higher channel capacities are also available upon request.
