Abstract: A method and apparatus are provided performing near-field measurements on dish antenna, in particular large dish antenna, and for utilizing these measurements to realign dish panels. The antenna is tiltable about a pivot point on a mounting pedestal to any desired elevation angle. A substantially circular track is provided which is centered at and spaced a predetermined distance from the pivot point, the track preferably being adjustably mounted to a stiff circular arch. The antenna is rotatable in the azimuth direction, preferably by rotating the pedestal, and a scanning probe is provided which is mounted for control traversal on the circular track. The probe is utilized to perform near-field measurements on the antenna at selected azimuthal positions of the antenna and selected positions of the probe on the track. The probe may also be rotatable to at least two different polarizations.
