Description

The Shure UA874 Active Directional Antenna is designed to provide reliable and focused wireless signal reception for both VHF and UHF wireless systems. Using a log periodic dipole array design, the antenna creates a cardioid pickup pattern that concentrates coverage in the desired direction while reducing interference from unwanted RF signals outside the target area. This makes it an excellent choice for live sound environments, conference spaces, theaters, and professional broadcast setups where stable wireless performance is essential.

An integrated amplifier with four selectable gain settings helps compensate for signal loss caused by longer coaxial cable runs, allowing for flexible system installation without sacrificing performance. The UA874 can be mounted on a stand, suspended from a ceiling, or attached to a wall using the included swivel adapter bracket, making it adaptable to a wide range of venue layouts and installation needs. Its durable construction and versatile mounting options make it a dependable addition to professional wireless audio systems.
