Description Improve wireless signal reception for UHF wireless systems with the Shure UA874WB, a wideband active directional antenna with a frequency range extending from 470 to 900 MHz. The antenna 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 1/2-wave omnidirectional antennas.An integrated amplifier with four gain settings compensate for varying degrees of coaxial-cable signal loss.The UA874WB can be stand-mounted, suspended from the ceiling, or wall-mounted using the integrated swivel adapter bracket.FeaturesShure quality, ruggedness, and reliabilityCompatible with Shure wireless receivers and antenna distribution systems that provide 10 to 15 VDC bias currentFour-position gain selector switchIntegrated threaded adapter mounts easily to microphone standsLow-noise signal amplifier compensates for insertion loss in coaxial cableSpecificationsRF Frequency Range470 to 900 MHzConnector TypeBNC, FemaleImpedance50 OhmsReception Pattern70°, 3 dB Beam WidthThird-order Overload Intercept Point
