The UH850S UHF CB handheld radio is the ultimate in compact UHF communications, with 5 Watt power and delivering up to 17km range. This makes it the perfect unit for professionals who need a rugged and heavy duty radio suitable for various conditions. The latest innovation added to the Uniden UHF range, Master Scan™ technology, is designed to ensure minimal disruptions for continuous communication, and allows users to seamlessly communicate on a group of channels. If your current channel is interrupted by outsiders, all radios in your group will automatically jump to a new clear channel allowing communications to continue.
