The Shure UA874US is an Active Directional Antenna with Gain Switch 470-698 MHz that 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 the greater rejection of RF signals outside the coverage area when compared to 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 stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
