This UHF antenna uses a log periodic dipole array to produce a cardioid pattern toward the desired coverage area, achieving greater rejection of RF signals outside the area than standard ½ wave omnidirectional antennas.
An integrated amplifier with four gain settings compensates for varying degrees of coaxial cable signal loss.
The UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
Compatible with all Shure wireless receivers and antenna distribution systems that provide 12 V DC bias
Four-position gain selector switch
Low-noise signal amplifier that compensates for transmission loss in coaxial cable
Integrated threaded adapter that mounts easily to microphones stands
Legendary Shure build quality and reliability

Shure UA-870WB Directional UHF Antenna
A Directional Antenna for Shure U4 and ULX Receivers!
The Shure UA870 is an active UHF wireless directional antenna featuring a log periodic dipole array. When compared to an omnidirectional 1/2-wave antenna, the cardioid pattern provided by the UA870 offers enhanced reception of the desired coverage area and greater rejection of RF signals outside the coverage area.
To compensate for coaxial cable signal loss, the UA870 has an on-board amplifier that offers user selectable 3 or 10dB gain. The gain setting is indicated by two LEDs. Remote 12 Vdc power for the antenna amplifier is provided by a Shure U4 receiver or a Shure UA840 antenna distribution system through the connecting coaxial cable.
The UA870 can be mounted on a microphone stand, suspended from the ceiling, or mounted to a wall using the integrated swivel adapter bracket. The UA870 is weather resistant for use outdoors. For best diversity performance, use two UA870 antennas.
The UA870WB is a UHF wideband (470-900MHz) active directional antenna for U4S, U4D, ULXP and ULXS receivers or UA844 and UA845 antenna distribution systems. |
