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.

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.

Use Shure low-loss coaxial antenna cable (or any 50 ohm, low-loss cable. The quality of the cable, not just the length, contributes to signal loss.

NOTE: When ordering cables from Shure, select the low-loss "Z" models (available for longer cables) when using frequency bands above 1000 MHz.

RF performance. Too much gain actually reduces reception range and the number of available channels. This is because Shure receivers are optimized to deliver the best performance when the sum of signal gain and cable loss equals 0 dB. Additional gain just amplifies everything in the RF range—including... -
