General

The Shure Model UA844SWB is a UHF antenna distribution system that allows 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 UA844SWB system can support up to four wireless receivers. A maximum of five UA844SWB systems may be used in a two-tiered configuration.
