Shure UA870USTV Active Directional Antenna (470-698 MHz)
Shure UA870USTVactive UHF wireless directional antenna is designed for use with select Shure UHF wireless receivers, and it also features a cardioid reception pattern which enhances reception of the desired coverage area while eliminating RF signals outside the coverage area. An on-board RF signal amplifier compensates for signal loss during long cable runs. The amplifier features a switch allowing users to select between 3 or 10dB gain.
The UA870 requires remote 12VDC power via connected U4 receiver or antenna distribution system. The antenna is completely weather resistant and can be mounted on a microphone stand, suspended from the ceiling, or mounted to a wall using the integrated swivel adapter bracket.
