The UA845UWB Ultra-Wide Band Antenna and Power Distribution System from Shure is a five-way active antenna splitter and power distribution system for Shure's wireless UHF-R, QLX-D, ULX, ULX-D, SLX, and BLX (BLX4R only) receivers. It allows four wireless receivers to use the same set of antennas, and cascade connectors allow connections to a fifth receiver or a second UA845UWB.

Featuring power connectors for distributing power to each receiver, the antenna system's RF signal amplification compensates for insertion loss from splitting the antenna input to multiple outputs. A button on the front panel switches between one of the five frequency bands from 174 to 1805 MHz. In addition, the unit comes complete with DC cables, bulkhead adapters, twelve BNC cables, a power cable, and a rackmount hardware kit.
