Shure UA845UWB Ultra-Wide Band Antenna Distribution System

The Shure UA845UW-B is an antenna and power distribution system designed to improve the performance and reliability of wireless microphone setups. It allows you to connect up to four receivers using a single pair of antennas, which simplifies your setup and reduces the need for multiple antenna pairs. If you need to expand further, the system includes cascade ports that let you add a fifth receiver or link additional UA845UWB units together.

This system actively amplifies RF signals to make up for any loss caused by splitting the signal between multiple receivers. It covers a broad frequency range from 174 to 1805 MHz and offers five selectable frequency bands, making it compatible with a wide variety of Shure receivers such as UHF-R, QLX-D, ULX, ULX-D, SLX, and BLX4R models. The UA845UW-B also provides power distribution, delivering stable 15V DC power to up to four receivers, which helps keep your wireless system organized and reduces the need for separate power supplies.

On the front panel, you’ll find easy-to-use controls for selecting frequency bands and LED indicators that alert you to input overloads, helping you monitor system status at a glance. The unit is designed for rack mounting and includes an internal power supply, making it a practical choice for both touring professionals and fixed installations in venues, theaters, or houses of worship. Whether you’re managing a small wireless setup or expanding a large-scale system, the UA845UW-B offers a reliable and efficient way to distribute antennas and power.
