Enhance UHF wireless system signal reception with the Shure UA874WB, a wideband active directional antenna designed for a frequency range of 470 to 900 MHz. Utilizing a log periodic dipole array, this antenna delivers a cardioid pattern that focuses on the desired coverage area while effectively rejecting RF signals outside that area, surpassing the performance of standard 1/2-wave omnidirectional antennas.

Featuring an integrated amplifier with four gain settings, the UA874WB compensates for signal loss caused by varying degrees of coaxial-cable attenuation.

Versatile installation options include stand-mounting, ceiling suspension, or wall-mounting using the integrated swivel adapter bracket.
