3 Antennas 16 Receivers RF Matrix-Multicoupler + Audio Matrix rack


3 Antennas 16 Receivers RF Matrix-Multicoupler + Audio Matrix rack


Developed for integration in a NATO project, this rack combines :

  • Antennas to receivers RF switching

  • Switching of voice/data channels and PTT signals

 In a configuration which includes the following main components:

  • qty 1 Power Supply panel, for generation of  all the necessary operating voltages 

  • qty 1Patch Panel, for manual switching between antennas and multicouplers

  • qty 1 Patch Panel, for manual switching between antennas and receivers

  • qty 3 Multicouplers, one for each antenna

  • qty 1 RF Antennas Matrix 3-16

  • qty 1 Audio/Data  Matrix  for voice/data/PTT channels

  • qty 4 Audio/Data Patch Panel.



Control of the operating functions can be local by keyboard and display or remote over a  RS-232/422 serial line, 9600 bit/sec.

The 3 Antennas 16 Receivers standard configuration  can be adapted  for different numbers of antennas and receivers without alteration of the rack layout.

 The rack is a compact, lightweight and  self-contained  structure made of aluminium alloys, removable panels allow easy access to all the internal parts for installation and servicing/maintenance and troubleshooting  during the operating life.


Advanced design and new-generation technologies have resulted in technical characteristics which set performance standards for this type of systems.
