Shure UA874E Active Directional Antenna

The Shure UA874 is an active directional antenna built on a log periodic dipole array, giving a cardioid pattern that rejects RF from outside the coverage area far better than a standard half-wave omni. An integrated amplifier with four gain settings compensates for cable loss. It can be stand, wall or ceiling mounted, and draws 12V DC bias over the coax from a compatible receiver or antenna distribution system. This is the E variant for European frequency bands.
