The Shure UA830 is a low-noise, in-line UHF antenna amplifier. It is intended for remote-mounting antennas to a Shure Model UR4 or ULX receiver or Model UA845, or UA844 distribution amplifier in a large installation, effectively shortening the distance from the transmitters.
The unit receives power through its output port from the Shure receiver or distribution amplifier. When an antenna is remote-mounted, the UA830 amplifies the received radio signals to compensate for insertion loss in the coaxial cable. A gain selector switch adjusts for longer lengths of coaxial cable.
