Shure UA874V Active Directional Antenna

Improve VHF wireless reception across live sound, broadcast and security deployments with the Shure UA874V Active Directional Antenna. This purpose-built antenna delivers focused, low-noise signal gain so your wireless receivers and monitoring systems capture stronger, more consistent audio in challenging RF environments. Designed for VHF operation (174–216 MHz), the UA874V includes an onboard low-noise amplifier and a four-position gain selector to compensate for varying coaxial cable losses and long runs. It accepts 10–15V DC bias from compatible Shure receivers or antenna distribution systems for seamless integration and predictable performance. The log-periodic directional design minimizes off-axis interference—ideal for surveillance, monitoring, and pro-audio applications where signal integrity matters. Rugged mounting options let you install it on a microphone stand, ceiling, or wall to match your site’s requirements. Add the Shure UA874V to your wireless toolkit to stabilize reception and reduce dropouts in live events, security monitoring, or broadcast workflows.
