Shure UA874US UN-0371 [Restock Item] UHF Active Directional Antenna with Integrated Amplifier

The UA874US Directional Antenna delivers improved wireless signal reception for VHF and UHF wireless systems. Features include rejection of RF signals outside the coverage area and an integrated amplifier with four gain settings.

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.
