About Shure UA874WB

The UA874 series of antennas delivers improved wireless signal reception for VHF and UHF wireless systems. Features include rejection of RF signals outside the coverage area and an integrated amplifier with four gain settings.

UA874WB 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 included swivel adapter bracket.

Shure UA874WB Features

  • Enhances wireless signal reception for Shure receivers and antenna distribution
  • Wideband frequency range from 470 to 900 MHz
  • Four-position gain selector switch for precise control
  • Low-noise signal amplifier for clearer audio
  • Compensates for coaxial transmission loss
  • Durable, rugged construction for reliable performance
  • Easily mounts to microphone stands
  • Includes integrated swivel threaded adapter
