The Shure UA845UWB is a high-quality, wideband UHF antenna distribution system that expands wireless microphone systems by splitting an antenna pair to multiple receivers. It provides five sets of outputs, allowing up to five wireless receivers to operate from a single pair of antennas, and includes cascade ports for connecting additional UA845UWB units. The unit also supplies 12V DC power for active antennas or in-line amplifiers, ensuring consistent signal strength over longer cable runs. Its robust design and wide frequency range make it ideal for professional live sound, broadcast, and installed AV applications requiring reliable multi-channel wireless performance.
