Shure UA830WB Active Remote Antenna Amplifier 470-900 Megahertz

The Shure UA830 is a low-noise, in-line antenna amplifier. The UA830 is intended for remote-mounting antennas to a Shure Model U4 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.
