Shure UA845 Wideband UHF 5-Way Antenna and Power Distribution System

The Shure UA845 is a UHF antenna distribution amplifier system designed to integrate with the Shure U4S, U4D, or UC4 wireless microphone receivers. The UA845 receives incoming RF signal using dual antennas, then distributes the signal via 4 BNC type connections. The UA845 also compensates for insertion loss by amplifying the signal on output. 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 directly from the UA845.
