The support uses a hollow shaft (8) extending perpendicular to a reference plane (2). This in turn supports a second shaft at right angles, via which the antenna (1) supported, at a required inclination and rotation angle relative to the reference plane (2). Each of the shafts (8,9) is rotated via a respective setting motor (6,7) supported by the reference plane, via a simple gear mechanism (10) and via a rack and pinion mechanism respectively. USE - For automatic adjustment of directional antenna.
