NOTE:

The Wireless Audio Link system is analog based and does not depend on digital or IP-based equipment to function. If satellite stations are fewer than 15 miles apart, we recommend GPS Frequency Stabilization to prevent inter-station interference (heterodyne).Wireless Audio Link range is up to 20 miles, quasi-line-of-sight. Low VHF operating frequencies will accommodate some terrain and foliage.
