  • Low-noise signal amplifier compensates for insertion loss in coaxial cable
  • Compatible with Shure wireless receivers and antenna distribution systems that provide 10-15 V DC bias
  • Integrated threaded adapter mounts easily to microphone stands
  • Four-position gain selector switch
  • Onboard RF overload LED indicator

The UA874 Active Directional Antenna from Shure can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.

UA874 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. Antenna is available in different frequency ranges.

The UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
