The Shure 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 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.

• Compatible with all Shure wireless receivers and antenna distribution systems that provide 12V DC bias
• Four-position gain selector switch
• Low-noise signal amplifier compensates for transmission loss in coaxial cable
