The Shure Model UA845UWB AntennaDistribution System allows four receivers to use the same set of antennas. Thecascade connectors allow connections to a fifth receiver or a second UA845UWB.There are also power connectors for distributing power to each receiver. RFsignal amplification compensates for insertion loss from splitting the antennainput to multiple outputs. A button on the front panel switches between one offive frequency bands from 174 to 1805MHz.
