Ok, so these antennas are not extrema geographically.
Can someone say if they are extrema in pointing/focus/collimation model
coefficient properties? (Relative to refant...)
Are those pads mechanically notable in any way?
(Hmm, do we have any capacity to safely/stably shim antennas on a
pylon?.... That could be a fun experiment.....)
