Shure UA874WB Active Directional Antenna UHF 470-900MHz Wideband

The UA874 series antennas represent a significant advancement in wireless signal reception technology for VHF and UHF systems. These sophisticated antennas excel at rejecting unwanted RF signals from outside your coverage area whilst incorporating an integrated amplifier featuring four distinct gain settings to optimise performance.

Built around a log periodic dipole array design, the UA874 generates a precise cardioid pattern that focuses on your desired coverage zone. This configuration provides superior rejection of external RF interference compared to standard ½ wave omnidirectional antennas. The integrated amplifier’s multiple gain settings effectively compensate for varying degrees of signal loss that occurs through coaxial cable runs.

Installation flexibility remains a key strength of the UA874, with mounting options including stand-mounting, ceiling suspension, or wall-mounting configurations. The included swivel adapter bracket ensures precise positioning to achieve optimal signal reception for your specific venue requirements.
