Shure UA834WB In-Line Antenna Amplifier for Remote Mounting (470 to 902 MHz)

The Shure UA834WB is a wideband in-line antenna amplifier designed to extend antenna cable runs in professional wireless microphone installations. Ideal for remote mounting applications, it allows antennas to be positioned closer to the stage or mounted on ceilings and walls, helping maintain optimal line of sight with wireless transmitters for improved RF performance.

Engineered to compensate for insertion loss in long coaxial cable runs, the UA834WB features a low-noise signal amplifier and a two-position gain selector switch with +6 dB and +12 dB settings. Built-in overload LED indicators provide visual confirmation of proper signal levels, helping prevent RF distortion.

The UA834WB is compatible with Shure wireless systems and integrates seamlessly with Shure UA845 and Shure UA844 antenna distribution systems.

For flexible installation, the amplifier includes an integrated threaded adapter for easy mounting to a microphone stand, as well as a supplied surface-mount bracket—making it well-suited for touring, installed sound, broadcast, and corporate AV environments where reliable wireless coverage is critical.
