The Shure UA874 is an active UHF directional antenna. It features a log-periodic dipole field. Compared to an omnidirectional half-wave antenna, the UA874 provides improved reception of the desired coverage area and greater suppression of RF signals outside the coverage area.To compensate for coaxial cable signal loss, the UA874 has a switchable amplifier with 4 settings that allows the user to accurately compensate for cable loss. Remote powering of the antenna amplifier with 12 Vdc is provided by a Shure AXT400, UR4, ULXD4 or ULXP4 receiver or a Shure AXT630, UA845 or UA844 antenna distribution system through the coaxial cable connection.The UA874 can be mounted on a microphone stand, suspended from the ceiling or mounted on a wall using the built-in swivel adapter bracket.
