The Shure UA830WB is intended for remote mounting antennas for Model U4 or ULX receivers, and Model UA845 or UA844 distribution amplifiers in a larger installation to effectively shorten the distance from the transmitters. If the antenna is remote mounted, it amplifies the received radio signals to compensate for insertion loss in the coaxial cable. This amplifier is mountable on a desk/wall mount or on a microphone stand.
