The Shure Model UA845 is an amplified, UHF Antenna Distribution System that expands a wireless microphone system by splitting one pair of antennas to multiple Shure UR4 or Shure UC4 wireless receivers. It also amplifies RF signals to compensate for insertion loss due to splitting signal power to mulitple output connectors. Each UA845 allows up to four receivers to use the same antennas. CASCADE connectors allows connections to a fifth receiver or a second UA845. There are also power connectors for powering Shure UHF and UC Wireless systems. NOT FOR USE WITH ULX.

Low Noise and Intermodulation Distortion. The UA845 maintains clean signals with minimal distortion
Insertion Loss Compensation. Whenever a signal is split to multiple output ports, there is a loss in signal strength. The UA845 amplifies signals to compensate, ensuring a strong signal to the receivers.
Front-Mounted Antennas. The UA845 comes with hardware to front-mount the antennas, if desired.
