TX RX Systems Brand

Control Station Combiner

43-83G-01A Series

Bird®, TX RX Systems Brand 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 while 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.

Single antenna-port mobiles may be connected to the combiners to provide operation on two-antenna
congurations (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 746-869 MHz band in standard configurations for 4, 8,12 and 16 capacities.
Other frequency bands and higher channel capacities are also available upon request.
