AUGUST 2016 UPDATE: Please note that this product has been discontinued and replaced with UA845UWB.
Five-Way Active Antenna Splitter and Power Distribution System for U4S, UR4S, U4D, and UR4D receivers; Five-Way Active Antenna Splitter for ULXD4, UXLD4D, ULXD4Q receivers; 470-952 MHz, covers SWB frequency range, internal switching power supply.
The Shure Model 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, UR4, ULXD4, ULXD4D, or ULXD4Q 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.
Expandability. The UA845-SWB UHF Antenna Distribution System is designed for large UHF, UHF-R, or ULX-D™ wireless systems. Each unit allows up to four wireless receivers to use the same two antennas, and the CASCADE ports allow connection to a fifth receiver or a second UA845-SWB.
Compatibility. The UA845-SWB is compatible with all Shure UHF, UHF-R, and ULX-D wireless microphone receivers operating within a compatible frequency range (see UHF Carrier Frequency Ranges in the Specifications section).
CASCADE Ports. Two 50 Ω, BNC-type antenna CASCADE ports allow an additional UA845-SWB unit or a fifth wireless receiver. A large wireless system can be run off of a single pair of antennas.
Power OUTPUT and OUT Connectors for Shure UHF and UHF-R® Wireless systems. Up to five U4 or UR4 receivers can be daisy-chained and powered from a single source via the Power OUTPUT connectors. DOES NOT APPLY TO ULX or ULX-D.
