Adjustable Gain

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.
