Not that Ive noticed.

I suspect most Americans are more comfortable with our own measuring system plus our ham bands where antenna formulas are still published in feet and inches.

CU on the 525 foot band, Carl? Seriously, I suspect that the reason why many of us work in meters when modeling is simply that some of the most useful software products default to that.

I never found a way to model an an antenna over anything but flat, level
ground. Not in EZNEC+ 5.0, anyway.

Has anyone modeled or have experience with a transmit vertical array, say a 4-square, over uneven ground? By uneven I mean a variance of up to 2 - 3
meters over the footprint of the array elements.
