S P E C I F I C A T I O N TITLE OF THE INVENTION: METHOD OF AND APPARATUS FOR SETTING DIRECTION OF A PARABOLIC ANTENNA RELATIVE TO A COMMUNICATING SATELLITE ABSTRACT OF THE DISCLOSURE A method of and apparatus for setting the direction of a parabolic antenna towards a broad- casting satellite, suitable for use in the case where a plurality of satellites are available for service. The elevation angle and the azimuth angle of the antenna with respect to each satellite are minutely adjusted while the state of receiving of waves from the satellite is watched, and the values of the elevation and azimuth angles for each satellite are stored in a memory section when the optimum state of receiving is attained. When the user selects one of the satellites through a select- ing section, a control section operates to activate a driving section to swing the antenna vertically and horizontally in accordance with the stored optimum data, thus directing the antenna correctly towards the designated satellite. - 1 -
