Shure UA874 Active UHF Richt Antenna

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.
