A three-axis antenna positioner has an X-Y over azimuth configuration, and includes an azimuth drive assembly, an X-axis drive assembly, and a Y-axis drive assembly. The method includes forming at least one fixed electrode on a substrate. The head comprises a deformable stop that is interposed between the second mounting member and the connector, the deformable stop being capable of not obstructing the relative positioning tolerance between the head and the connector, and of abutting against the second mounting member by pressing against the connector in the first direction.
