MODEL UA845 ANTENNA DISTRIBUTION SYSTEM

The Shure Model UA845 is an amplified, UHF Antenna Distribution System 

that expands a wireless microphone system by splitting one pair of antennas 

to multiple Shure UR4 or Shure ULX4 wireless receivers.  It also amplifies 

RF signals to compensate for insertion loss due to splitting signal power to 

mulitple output connectors. Each UA845 allows up to four receivers to use 

the same antennas. CASCADE connectors allows connections to a fifth re-

ceiver or a second UA845.  There are also power connectors for powering 

Shure UHF Wireless systems.Each system contains the following items:

UA845 Antenna Distribution System

Rack-mounting hardware

Surface-mounting hardware 

Front-mounting antenna hardware

18-in. Power OUTPUT Cord

Power Cord

Antenna cables for receiver connections

The Shure Model UA845 ensures maximum sensitivity and signal processing 

capability, providing the widest radio range possible for the largest number 

of wireless receivers. To get the most from this system, follow these guide-

lines: 

When using long runs of cable for remote-mounted antennas, use the 

UA830 In-Line RF Amplifier and the Shure Model UA825 or UA850 Re-

mote Antenna Extension cables (RG-8/X or equivalent), which have low 

loss at UHF operating frequencies

Locate multiple transmitters more than 3 m [10 ft] from receiving 

antennas

SYSTEM FEATURES

Expandability. The UA845 UHF Antenna Distribution System is designed 

for large UHF wireless systems. Each unit allows up to four wireless re-

ceivers to use the same two antennas, and the CASCADE ports allow con-

nection to a fifth receiver or a second UA845.

Compatibility. The UA845 is compatible with all Shure wireless micro-

phone receivers operating within a compatible frequency range (see 

UHF 

Carrier Frequency Ranges 

in the Specifications section).

CASCADE Ports. Two 50 

, BNC-type antenna CASCADE ports allow an 

additonal UA845 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. Up to five (5) UR4 receivers can 

be daisy-chained and powered from a single source via the Power OUT-

PUT connectors.  

Low Noise and Intermodulation Distortion. The UA845 maintains clean 

signals with minimal distortion.

Insertion Loss Compensation. Whenever a signal is split to multiple out-

put ports, there is a loss in signal strength. The UA845 amplifies signals 

to compensate, ensuring a strong signal to the receivers.

Front-Mounted Antennas.  The UA845 comes with hardware to 

front-mount the antennas, if desired.

CONTROLS AND CONNECTORS

AC Power INPUT Connector. 

AC Power OUTPUT Connector. Each UA845 has a Power

OUTPUT connector for daisy-chaining up to five (5) Shure

Model UR4 UHF Diversity Single or Dual Receivers to a

single power source.

NOTE:  This connector does not work for Shure ULX4 Receivers.  

ANTENNA IN Ports, Channel A & B. BNC-type connectors

for antennas.

RF CASCADE Connectors (Output connector 5), 

Channel A & B. BNC-type connectors for adding a fifth

receiver, or additional UA845's, permitting more wireless

receivers to be connected.

RF OUTPUT Connectors, Channel A & B. BNC-type con-

nectors for up to four wireless receivers.
