Hi Mark,
Let's talk about your PRESENT tower for a minute . . .

How were you able to tip it over at all? Is it mounted on a hinged base?
If it is, Rohn says it must be guyed. I hope it is.
It was a two man

Rohn makes a tiltover kit for 25G. It's expensive and it has to be guyed,
but it will work like you want it to.

I have never seen one of the towers you descibed as you saw at the airport.
Sorry, can't help you there.
