Shure UA845UWB Five-Way Active Antenna and Power Distribution System for QLX-D, ULX, ULX-D, SLX, and BLX4R Wireless Receivers

Shure UA845UWB — Five-Way Active Antenna and Power Distribution System

The Shure UA845UWB is a professional five-way active antenna and power distribution system designed to simplify and optimize multi-channel wireless microphone installations. It allows multiple compatible Shure wireless receivers to share a single pair of antennas while also distributing DC power to connected receiver units.

Designed for professional live sound, broadcast, theater, and installed AV applications, the UA845UWB helps reduce antenna clutter and improve RF system organization in large wireless setups. Its active circuitry compensates for signal loss caused by cable splitting, helping maintain strong and stable RF signal performance across connected receivers.

The system supports wideband UHF frequency operation and is compatible with several Shure wireless receiver series, including QLX-D, ULX, ULX-D, SLX, and BLX4R systems. It provides cascade ports that allow multiple distribution units to be linked together, making it suitable for expanding wireless systems with higher channel counts.

The UA845UWB also includes built-in power distribution, allowing compatible receivers to receive power directly from the distribution system using supplied DC cables. This helps streamline rack installations by reducing the number of required external power supplies and simplifying cable management.

Built for professional rack-mounted environments, the UA845UWB is ideal for venues and productions requiring reliable wireless performance, organized antenna distribution, and scalable system expansion.
