Shure UA874XA Active Directional Antenna (902-960 MHz)

Active Directional Antenna with Gain Switch (902-960 MHz)

The UA874 series of antennas 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 1/2 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.

Features:

• Compatible with all Shure wireless receivers and antenna distribution systems that provide 12 V DC bias
