In this paper I demonstrate how our current technology now very readily permits a standard of accuracy and utility to be realized, that was formerly available only in research laboratories. This is accomplished with standardly available positioning equipment and standardly available software. Accurate alignment of the range is enabled by a tracking laser interferometer. This composite near-field scanning antenna range has afforded us the opportunity to compare readily, far-field results from the classic planar, cylindrical and spherical coordinate systems. Comparison data are presented.
