Shure UA874E UHF Active Directional Antenna

Item No 32137
The UA874 replaces the UA870. 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 ½ wave omnidirectional antennas. An integrated amplifier with four gain

FEATURES

  • Compatible with all Shure wireless receivers and antenna distribution systems that provide 12V DC bias
  • Four-position gain selector switch
  • Low-noise signal amplifier compensates for transmission loss in coaxial cable
  • Integrated threaded adapter mounts easily to microphone stands
Description
The UA874 replaces the UA870. 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 ½ wave omnidirectional antennas. An integrated amplifier with four gain settings compensate for varying degrees of coaxial cable signal loss.

The UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
UA874 is available in two different versions:
  • UA874E = 470 - 790 MHz
  • UA874WB = 470 - 900 MHz
