Abstract
Radio antennas are aligned with each other for the creation of a fixed radio link, by temporarily mounting a powered actuator on an antenna forming one end of the link, the actuator being arranged to adjust the alignment of the antenna, controlling the movement of the actuator over a range of alignments, measuring the variations in the properties of a signal transmitted over the link as the actuator is moved, identifying an optimum actuator position, and locking the actuator in the optimum position. By using a powered antenna, it is possible to control the alignment of several antennas from a single convenient location. Once the antenna has been secured in the selected position the powered actuator may be recovered for use elsewhere.
