Radio Active Designs has introduced the production community?s first ever Enhanced Narrow Band? wireless intercom system. Enhanced Narrow Band? offers RF channels possessing an occupied bandwidth of a mere 25 kHz with the audio characteristics one would expect from a traditional FM system. The UV-1G also utilizes the relatively unused VHF range for all belt pack portable devices. This leaves more room for operation of other wireless devices, such as In-Ear Monitors and Wireless Microphones.
