Wireless Microphones

The Shure UA874 Active Directional Antenna is an adaptable solution with its own integrated amplifier for excellent wireless signal reception. This antenna gives you the ability to turn the amplifier off and even lets you attenuate the signal, so you can protect the front end of your receiver – even in high-noise situations. The UA874 works with all Shure wireless receivers and antenna distribution systems that supply 12V DC bias. With its log periodic dipole array, the UA874 produces a cardioid pattern aimed at your desired coverage area, and rejects RF signals from the rear. Get superior wireless performance with the Shure UA874.

Low-noise amplifier with four gain settings gives you amazing flexibility

The Shure UA874 features the same low-noise amplifier Shure uses in their Axient system. The UA874 is the only directional antenna that sports active, passive, and attenuated gain settings, as well as an RF overload indicator. The amp’s four gain settings let you compensate for varying amounts of coaxial cable signal loss.

An excellent choice for high-performance wireless systems

Shure’s UA874 significantly improves the quality of the amplifier over previous designs, greatly reducing IM distortion, and noise. The UA874’s robust capabilities makes it an excellent antenna choice for Shure’s cutting-edge Axient and ULX-D systems, allowing a full measure of performance from both.

Achieve great wireless results – even under adverse conditions

Adaptable to a variety of in-field wireless challenges, the UA874 antenna can be stand-mounted, suspended from the ceiling, or wall-mounted using an optional swivel adapter bracket. The UA874 gives you the flexibility to achieve superior wireless results, even in the most inimical production environments.
