Five-Way Active Antenna Splitter and Power Distribution System for Axient Digital, UHF-R, QLX-D, ULX, ULX-D, SLX and BLX (BLX4R only) receivers.

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

Shure UA845UWB Features:

  • 5 selectable frequency ranges.
  • Antenna A and B input overload LED indicators.
  • Five-way RF signal output.
  • Support Axient Digital, QLX-D, ULX, ULX-D, SLX, and BLX (BLX4R only) receivers.
  • Front-mounting antenna hardware.
  • Rack-mounting hardware.
  • Internal power supply.
  • 4 DC power feeds for receivers (15V, 2.5A max.)
  • DC outputs for antenna bias (12V, 300mA max.)
UA845UWB Band Selection on the Front Panel
  • 174 - 216 MHz
  • 470 - 960 MHz
  • 1240 - 1260 MHz
  • 1492 - 1525 MHz
  • 1785 - 1805 MHz
