摘要
For use with an antenna tower, the antenna tower providing a mount for an active antenna that is subject to misdirection when the antenna tower sways, a system for, and method of, dynamically counteracting sway in the antenna tower. The system includes: (1) a rotation detector that senses a rotation, relative to a fixed reference plane, of a portion of the antenna tower proximate the active antenna and develops a sway signal indicative thereof and (2) antenna beam steering logic, coupled to the rotation detector, that receives the sway signal and modifies a drive signal provided to elements of the active antenna to redirect a beam projecting therefrom, the drive signal thereby compensated for the rotation to counteract the sway in the antenna tower. The system may form a portion of a wireless communications station.
