I'm certainly no mechanical engineer, but that ratio is a typical rule of
thumb for SS towers that are in the "practical" range that you and I see.
I can only imagine the mechanical issues involved in building a self
supporting structure 2,000 ft. tall!!
The CN Tower in Toronto is the world's tallest tower structure, at 1,815 ft.
5 in.
But it is made of concrete.

We have one SS tower, under 300' but the legs are about 64' apart, IIRC.
But you mentioned 4-sided & ours has only 3.

For a typical 10:1 ratio on SS towers, it would be 200' at the base.
That height would make a square tower able to be more stable than a
triangular one, but still that would be less than one acre of land.

Wow, I wonder how much that study cost us...
Maybe all tall, guyed, towers should be replaced with self-supported
towers...
I wonder how much land a 2000' seld-supported tower would require...

The Georgia Association of Broadcasters sent us info on the NPRM for bird
mortality. Here are two astute observations in the report:
That all other things being equal, taller towers with lights tend to
represent more of a
hazard to birds than shorter, unlit towers;
That towers with guy wires create higher risks than self-supporting towers;
