Shure UA874 Active Directional Antenna with Gain Switch
The Shure UA874 is a compact, high-performance active directional antenna designed for professional wireless microphone and in-ear monitoring systems. Built for reliable RF reception in challenging environments, it combines directional gain with user-adjustable amplification to optimize signal strength and reduce interference.
Features:
Directional pattern: Focused reception improves gain on intended transmitters while rejecting off-axis noise and interference.
Built-in preamplifier: Integrated active electronics boost weak signals for longer range and clearer reception.
Gain switch: Selectable gain settings allow quick adaptation to different operating conditions — reduce gain to avoid overload in high-RF environments or increase gain for distant transmitters.
Rugged construction: Durable housing and corrosion-resistant connectors for dependable use in touring, live sound, and rental applications.
Low-noise performance: Designed to preserve signal integrity and minimize added noise from the preamp.
Easy mounting: Standard mounting options for placement on stands, racks, or antenna poles to suit stage and venue layouts.
Applications:
Live sound and touring
House of worship and corporate events
Theaters and broadcast studios
Wireless mic and IEM systems where directional reception and adjustable gain improve reliability
Compatibility and connectors:
Works with Shure wireless receivers and many professional wireless systems that accept BNC antenna inputs.
Typically features BNC connectors and standard antenna cable interfaces.
Why choose the UA874? The UA874 offers a practical balance of directional performance and flexible gain control, making it a reliable choice for engineers and technicians who need cleaner RF reception in varied venue conditions. Its rugged design and straightforward operation make it well-suited for both permanent installs and road use.
What to consider
Proper aiming and placement are important to maximize directional benefits.
In extremely RF-dense environments, start with lower gain settings to prevent receiver overload.
Use quality coax and connectors to maintain optimal signal transfer between antenna and receiver.
The UA874 can be mounted on a microphone stand, suspended from the ceiling or mounted to a wall using the integral swivel adapter bracket.
Note: Verify the specific UA874 variant for exact frequency range, connector type, and gain figures to ensure compatibility with your wireless system.
