Abstract
In a method for alignment of an antenna (1) with an adjustable directional characteristic in a mobile station in a mobile radio system, the alignment process is based on determination of two variables as a function of the direction, with the first variable being characteristic of the signal strength (6) and the second variable being characteristic of the signal quality (5, 15), and their evaluation (7). Furthermore, it is possible to make use of position information and alignment information relating inter alia to satellite-based navigation systems, and to take account of the alignment of the user.
