Hi The thing I’m not quite understanding here - why in the world use an antenna that needs a ground plane when you can get one that does not need an external ground plane?
I have three multi band GNSS antennas on the back of the house. They all get down to insane error circles (like a mm) according to Opus. None of them have or need external ground planes. The survey guys got away from giant ground planes a long time ago. They seem to be quite happy with the results they get.
