ATC CM-300/350 Series VHF/UHF Transmitter/Receiver
ATC Rackmount 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 will be the first radios deployed in the NAS to support VoIP global standards. A standardized radio means you have 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.
Your radios will work for a very long time. The CM-300 Series radios boast unprecedented Mean-Time-Between-Failure (MTBF) rates, meaning you won’t have to worry about the radio breaking down.
