Shure UA874WB Wideband Active Directional Antenna (470 to 900 MHz)


Improve wireless signal reception for UHF wireless systems with the Shure UA874WB, a wideband active directional antenna with a frequency range extending from 470 to 900 MHz. The antenna uses a log periodic dipole array to produce a cardioid pattern towards the desired coverage area with greater rejection of RF signals outside the coverage area when compared to standard 1/2-wave omnidirectional antennas.

An integrated amplifier with four gain settings compensate for varying degrees of coaxial-cable signal loss.

The UA874WB can be stand-mounted, suspended from the ceiling, or wall-mounted using the integrated swivel adapter bracket.

  • Shure quality, ruggedness, and reliability
  • Compatible with Shure wireless receivers and antenna distribution systems that provide 10 to 15 VDC bias current
  • Four-position gain selector switch
  • Integrated threaded adapter mounts easily to microphone stands
  • Low-noise signal amplifier compensates for insertion loss in coaxial cable
