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 
the post.

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.
