The Shure Model UA844+SWB is an antenna distribution system that allows for the expansion of wireless microphone systems by splitting one pair of antennas to multiple receivers. It also amplifies RF signals to compensate for insertion loss that results from splitting signal power to multiple outputs. A single UA844+SWB system can support up to five wireless receivers. A maximum of five UA844+SWB systems may be used in a two-tiered configuration.
