The Shure UA845-SWB is an amplified, UHF Antenna Distribution System that expands a wireless microphone system by splitting one pair of antennas to multiple Shure U4 or Shure UR4 wireless receivers. It also amplifies RF signals to compensate for insertion loss due to splitting signal power to multiple output connectors. Each UA845-SWB allows up to four receivers to use the same antennas. CASCADE connectors allow connections to a fifth receiver or a second UA845-SWB. There are also power connectors for powering Shure UHF and UHF-R Wireless systems.
