Abstract

An antenna tower adjusts a subscriber beam in elevation to reduce cell interference. The antenna tower includes vertically spaced antennas that generate a subscriber beam that may be precisely adjusted in elevation. The antenna tower may also periodically calibrate the subscriber beam in order to precisely point the subscriber beam in a desired direction.
