The Shure Model UA844 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 outlets. A single UA844 system can support up to four wireless receivers. A maximum of five systems may be used with a two-tiered configuration (see user guide).
