@User: Sorry, the antenna check output is in internal coordinates, and the internal grid may be at some unusual scale. Use "snap int" followed by "box values 166905 4091 166963 4097" to reach the area. Also note that antenna violations are saved as feedback areas, so you can do "feedback find" and get to the error. The feedback entries should be in the same order as the antenna violation output, which means that "feedback find 1" should get you to the first error, and so forth, if there are multiple violations.
