There were pictures somebody posted some years ago from Canada showing collapsed 300' 25G towers. I think that was during a major ice storm. I've heard of 300' 25G's but you wouldn't catch me climbing them. 45G would be iffy. I have one of those that is 200' I've never personally climbed but my guys say its pretty solid.
For footprint, figure guy anchors at 80% of the tower height in three directions.

We DO have two 190s in the air, but we beefed up the guying including two anti-twist sections (our own design). Even on 120 ft. we do an anti-twist. Rohn 45 is more suitable for 200ft + but at 250, I would be looking at Rohn 55/65 for sure. (with anti-twists as well). The Rohn site has all you need on footprints etc. Cost… texastowers.com can give you a quote From: Af [mailto:[email protected]] On Behalf Of TJ Trout Sent: Sunday, May 31, 2015 3:05 AM To: [email protected] Subject: Re: [AFMUG] Rohn free standing I don't know why I wrote freestanding, I meant guyed, obviously....

Even guyed, I think it would be a rather frightening experience...
