UA874 uses a log periodic dipole array to produce a cardioid pattern towards the desired coverage area with greater rejection of RF signals outside the coverage area when compared to standard ½ wave omnidirectional antennas.
The Shure UA874US uses a log periodic dipole array to offer enhanced reception when directed toward the desired coverage area. An integrated amplifier and four gain settings compensate for varying degrees of coaxial cable signal loss. The UA874US can be mounted on a microphone stand, suspended from the ceiling, or mounted to a wall using the integrated swivel adapter. Low-noise signal amplifier compensates for insertion loss in coaxial cableCompatible with Shure wireless receivers and antenna distribution systems that provide 10–15 V DC biasIntegrated threaded adapter mounts easily to microphone standsFour-position gain selector switchShure quality, ruggedness, and reliability
Active directional antenna with gain switch 470-698 MHz.
The Shure UA874US Active Directional Antenna with Gain Switch is an advanced, high-quality solution designed to enhance your wireless audio experience. The integrated amplifier and four selective gain settings ensure that signal losses caused by the coaxial cable are compensated for effectively.
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.
