The Shure UA834V Antenna Amplifier is designed for large wireless installations, adding flexibility in antenna placement.
By amplifying the RF signal to compensate for losses associated with long coaxial cables, this model ensures optimal reception even in complex environments. Compatible with several Shure receivers, including the UR4, ULX and QLX-D, it allows antennas to be positioned closer to the stage or in strategic areas to improve line-of-sight with transmitters for optimal transmission.

The Shure UA834V features an integrated threaded adapter, making it easy to mount on microphone stands or wall brackets. With a two-position adjustable gain selector, you can choose between +6 dB and +12 dB depending on the length of the cable used, optimizing system performance.
A control LED constantly monitors the RF signal, warning of overload. This product is powered directly through the antenna cable by the receiver or a splitter.

Ideal for remote antennas, this amplifier adapts to different types of coaxial cables and guarantees stable RF performance in all circumstances. Made with a robust aluminum housing, it is designed to withstand the demanding conditions of professional installations, while remaining lightweight and easy to install.
