Catch pattern problems early.<\/p>\n\n<\/div>\n\n\n Research & universities<\/strong> \u2014 independent measurement data for papers, theses, or grant reports. Repeatable methodology.<\/p>\n\n<\/div>\n\n<\/div>\n\n<\/div><\/div>\n\n\n\n The antenna tracker does not follow a simple up-down\/left-right grid. Instead, it uses a point distribution that spreads measurement samples evenly across the full sphere \u2014 so every region of the radiation pattern gets the same angular resolution. A conventional elevation\/azimuth scan bunches points near the top and bottom of the sphere and thins out around the equator. Our approach avoids that, producing a cleaner, more complete picture of antenna performance. The traversal order between measurement points is further optimised as a shortest-path problem, minimising total tracker travel and keeping measurement campaigns as short as possible. The plot below shows the measurement point locations and the tracker path \u2014 click Traversal Path<\/strong> in the legend to show or hide the path.<\/p>\n\n\n\n\ud83d\udccb What You Get<\/h3>\n\n\n
