Air Traffic Control Rackmount Transmitter and Receiver Systems

Air Traffic Control (ATC) radios need to keep pace with the demanding volume of air traffic. Knowing that your ATC radios can perform well in a high stress environment helps to make your job a little less stressful.

  • Winner of FAA’s NEXCOM Segment 2 — The CM-300/350 (V2) VHF/UHF radios are the first deployed in the National Airspace System that support VoIP global standards. Standardized radios mean less costs and more flexibility with your radio equipment.
  • Remote Maintenance and Monitoring lets you support an almost unlimited number of radios from one location.
  • High Reliability - The CM-300 Series radios boast unprecedented Mean-Time-Between-Failure rates, meaning you won’t have to worry about the radio breaking down.
