Clarity™ Noise Reduction Technology– 721S Family of V/UHF Radios

Increase your mission success with Clarity noise reduction technology. Clarity significantly reduces background noise in transmit and receive modes by removing non-syllabic audio (e.g., cockpit/aircraft noise, heating/cooling system noise, street and office sounds, and signal interference from co-location pollution). The result is a clean and uncluttered communication signal between ground radio operators and pilots with improved power and transmission distance.
