SHURE UA874WB Active, directional antenna (470-900 MHz)

Product Details:

• Shure UA874 is a directional, active UHF antenna to help improve wireless system reception and signal integrity.
• 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.
• 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 includes active, passive and attenuated settings
• Onboard RF overload LED indicator
• Low-noise signal amplifier compensates for transmission loss in coaxial cable
• Integrated threaded adapter mounts easily to microphones stands
