The UA844+SWB UHF Wideband Antenna Distribution System from Shure is for the expansion of a Shure wireless microphone system. It can be used to split one pair of antennas to multiple receivers and amplify the RF signal to compensate for the insertion loss.

A single UA844+ system can support up to five wireless receivers. A maximum of five UA844+ systems may be used in a two-tiered configuration. The system is compatible with the Shure QLX-D, ULX, ULX-D, SLX, and BLX4R wireless receivers.
