43-83G-01A Series

43-83G-01A Series, 746-869 MHz, Multi-Channel Control Station 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 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 will support frequencies from 746 MHz to 869 MHz and are available in 4 channel increments from 4-32 channels.

  • Low Profile for Space Efficient Installation
  • Frequency Agile with Predictable Isolation
  • Analog and Digital Compatible
  • Duplexer and Triplexer Recommended to be used in conjunction with Control Station Combiners
