The Shure UA845 UHF Antenna Distribution System simplifies the deployment of multiple wireless microphone systems by distributing RF signals from a single pair of antennas to several receivers. Designed for professional audiovisual applications, this antenna distribution system improves signal reliability, reduces antenna clutter, and supports scalable wireless microphone setups for conferences, live performances, worship services, broadcast productions, and special events. Compatible with a wide range of UHF wireless systems, the UA845 is an ideal solution for productions requiring dependable RF performance.

Wide UHF Frequency Compatibility

Operating across the 400–970 MHz UHF frequency range, the system distributes RF signals to up to five wireless receivers, making it suitable for professional stage productions, weddings, conferences, outdoor events, and broadcast applications.

Expandable Wireless System

Built-in cascade ports allow the antenna distribution system to connect to an additional distribution unit or a fifth wireless receiver, providing an easy path for expanding larger wireless microphone systems while using a single pair of antennas.

Dual Active Antenna Support

Two active directional antenna paddles provide high-gain RF amplification to compensate for signal loss and maintain stable wireless reception over long operating distances. This design helps deliver consistent RF performance in demanding production environments.

Integrated Power Distribution

A universal AC 100–260V internal power supply supports worldwide operation, while four integrated 12V DC power outputs can power compatible wireless microphone receivers, reducing cable clutter and simplifying equipment rack installations.
