Shure
  • UA874 active directional antenna 
  • General Description

    The Shure UA874 USES a logarithmic periodic dipole array to provide optimum reception when the required coverage area is available. The integrated amplifier has four gain Settings to compensate for the loss of coaxial cable signals at different levels. The UA874 can be fixed on the microphone holder, or it can be suspended from the ceiling or fixed on the wall with an integrated rotary support.
