UA834 

 

 

In-Line Antenna Amplifier

General Description

The UA834 provides more flexibility in wireless installations by increasing the allowable length of cable runs between a receiver 

and antenna. Antennas may be placed closer to the stage, or installed on ceilings and walls that maintain a better line of sight 

with the transmitter.

Features

Low-noise signal amplifier compensates for insertion loss in coaxial cable

Compatible with Shure Wireless Systems. Also may be used with Shure UA845 and UA844 Antenna Distribution Systems

Integrated threaded adapter mounts easily to microphone stands or the supplied surface-mount bracket

Two-position gain selector switch

LED indicator for RF signal overload

Shure quality, ruggedness, and reliability

NOTE: 

Antenna amplifiers are intended to compensate for signal loss in cables, not for increasing the range of the antenna. Attempting to “boost” the signal 

beyond nominal levels only results in overloading the circuit and reducing performance.

Indicators and Settings

 

DC POWER

/

RF OVERLOAD

Green: 

Indicates it is receiving power from the antenna input on the receiver or combiner.

Red: 

Signal from the antenna (at the 

TO ANTENNA

 input) is too strong. Remove the inline amplifier or move it further down 

the cable run.

 GAIN

Set the gain switch to +6 dB for shorter cable runs, and +12 dB for longer runs.

RF Overload

RF overload can occur at the input to the inline amplifier or at the input to the receiver. An overload at either point degrades the 

signal.
