Down Tilted Antenna (DTA)
In most situations, the base stations are installed on high towers or high roof-tops where the signals to and from the users are impinging the base station at high elevation angles. It is therefore preferable to tilt the antenna beam to provide good coverage to the users below.This tilting significantly reduces the level of interference since most of the interfering sources are impinging from the horizon and thus will be suppressed by a tilted beam.
DTA enables this beam tilting both in its Omni base stations, by a proper design of its omni-directional antennas, and in its Sector base stations, by allowing simple and flexible mechanical tilting.
