Shure UA874US Active Directional Antenna (470-698 MHz)

Active Directional Antenna with Gain Switch (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 1/2 wave omnidirectional antennas.

An integrated amplifier with four gain settings compensates 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.
