Shure UA874XA Active directional antenna with gain switch. (902-960 MHz)

Active directional antenna covering 902 to 960 MHz for Shure wireless microphone systems. A log periodic dipole array produces a cardioid pattern that rejects RF arriving from outside the coverage area, while an integrated low noise amplifier with a four position gain switch compensates for coaxial cable loss. It works with Shure receivers and antenna distribution systems supplying 12 V DC bias and mounts to mic stands, walls, or ceilings with the included swivel bracket.
