49 years ago I helped do an EZway tower with the "Wonder Ground Post",
rocket fins on the bottom of the post.
The owner (one of them engineers) did the math for a round disk, 3' in
diameter, 4" thick of concrete flush with ground level, not sticking to
He came up with some considerable multiplication of tilt over forces,
which I forgot, 48 years ago.
Someone with a bigger brain might try to apply the idea to the guy posts
and let us know some numbers.
