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.
