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 UC4 wireless receivers. It also amplifies RF
signals to compensate for insertion loss due to splitting signal power to mu-
litple output connectors. Each UA845 allows up to four receivers to use the
same antennas. CASCADE connectors allows connections to a fifth receiver
or a second UA845. There are also power connectors for powering Shure
UHF and UC 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
• DC power cables for receiver connections to DC power connectors on UC
receivers.
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 anten-

UHF Antenna Distribution System

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
Carrier Frequency Ranges
•
CASCADE Ports. Two 50 W, 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. Up to four (4) UC4 receivers can be powered from the
UA845 using the 12 Vdc OUT 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.
