Shure Brothers Inc UA874V Active Directional Antenna

Product Description

The SHURE BROTHERS INC UA874V is an active directional antenna designed to extend and improve wireless signal reception in professional audio and communication systems. Active antennas incorporate built-in amplification circuitry, compensating for cable loss over longer cable runs between the antenna and connected wireless receivers. The directional design focuses reception on a defined coverage zone, reducing interference from signals outside that zone. Installation is typically handled by audio-visual technicians or communications system integrators working in commercial, broadcast, or live-event environments.

The UA874V is suited for use in installations where wireless microphone systems or wireless monitoring systems require remote antenna placement. Typical applications include houses of worship, theaters, conference facilities, broadcast studios, and live-performance venues where antenna placement must be separated from the receiver rack to achieve adequate coverage and signal quality.

Key Features

• Active design with built-in amplification to offset cable loss on long antenna runs
• Directional pickup pattern for focused coverage and reduced out-of-zone interference
• Sold as a single unit for flexible deployment in distributed antenna systems

Compatibility

Designed as an OEM-style replacement or system-expansion antenna compatible with professional wireless receiver systems requiring an active directional antenna input.

Installation Notes

Installation should be performed by a qualified audio-visual technician or licensed communications systems integrator. Power down all connected wireless receivers before making antenna connections. Route coaxial cabling according to the manufacturer guidelines to avoid signal degradation, and observe applicable low-voltage wiring codes for the installation jurisdiction.
