Active Directional Antenna, 470-698 MHz
Experience improved wireless reception with the UA874. This UHF antenna uses a log periodic dipole array to produce a cardioid pattern toward the desired coverage area, achieving greater rejection of RF signals outside the area than standard ½ wave omnidirectional antennas.
An integrated amplifier with four gain settings compensates for varying degrees of coaxial cable signal loss.
The UA874 can be mounted on a mic stand with the integrated threaded adapter.
Compatible with all Shure wireless receivers and antenna distributionsystems that provide 12 V DC bias
Four-position gain selector switch
Low-noise signal amplifier that compensates for transmission loss incoaxial cable
Integrated threaded adapter that mounts easily to microphones stands
