  • The Shure UA870WB is an active UHF wireless directional antenna for Shure wireless systems. When compared to an omnidirectional 1/2-wave antenna, the Shure UA870's cardioid patterns offers enhanced reception of your desired coverage area and greater rejection of RF signals outside that area. An onboard amplifier compensates for coaxial cable signal loss, though the UA870 does require an appropriate Shure receiver or Antenna Distribution System to distribute power through the connecting coaxial cable. Mic stand-, wall-, and ceiling-mountable, the Shure UA870 is also weather resistant for use outdoors.

    • UA870WB (470-900mHz) RF Frequency Range
    • Active UHF wireless directional antenna

    • Onboard amplifier with user-selectable 3 or 10dB gain

    • Can be mounted on a microphone stand, suspended from the ceiling, or mounted to a wall using the integrated swivel adapter bracket
