UA845UWB
Antenna Distribution System
General Description
The Shure Model UA845UWB Antenna Distribution System allows up to four receivers to use the same set of antennas. 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. Cascade connectors allow connections to a fifth receiver or a second
UA845UWB. A button on the front panel switches between one of five frequency bands from 174 to 1805 MHz.
System Features
The Shure Model UA845UWB ensures maximum sensitivity and signal processing capability, providing the widest radio range
possible for the largest number of wireless receivers.
•
5 Selectable Frequency Ranges The UA845UWB allows more options for avoiding intermodulation artifacts by switching
between one of the five frequency bands.
•
RF Power LED Indicators Front panel LED indicators display red if RF power is overloading.
•
Expandability The UA845UWB Antenna Distribution System is designed for large 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 UA845UWB.
•
Compatibility The UA845UWB is compatible with all Shure wireless microphone receivers operating within a compatible
frequency range.
•
Cascade Ports Two 50 ohm, BNC-antenna cascade ports allow an additional UA845UWB 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 Multiple receivers can be daisy-chained and powered from a single source via the
power output connectors.
•
Low Noise and Intermodulation Distortion The UA845UWB maintains clean signals with minimal distortion.
•
Insertion Loss Compensation Whenever a signal is split to multiple output ports, there is a loss in signal strength. The
UA845UWB amplifies signals to compensate, ensuring a strong signal to the receivers.
•
Front-Mounted Antennas The UA845UWB comes with hardware to front-mount the antennas, if desired.
