The Shure UA874 is a UHF active directional antenna that delivers improved wireless reception.
It 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.
Features:
- Compatible with all Shure wireless receivers and antenna distribution systems that provide 12V DC bias
