Shure UA874US Active Directional UHF and VHF Antenna Delivers Improved Wireless Signal Reception With Integrated Amplification.

The Shure UA874 Active Directional Antenna uses a log periodic dipole array to offer enhanced reception when directed toward the desired coverage area. An integrated amplifier and four gain settings compensate for varying degrees of coaxial cable signal loss. The UA874 can be mounted on a microphone stand, suspended from the ceiling or mounted to a wall using the integrated 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
