Well, it depends. What's your county windspeed rating? If you don't
know, you can find it at
_http://www.championradio.com/county.windspeed.data.html_
(http://www.championradio.com/county.windspeed.data.html) . It's the
minimum - your local building department may have deemed it higher.
A free-standing 45G can go to around 35' with your load @ 80 MPH. Rohn
specs allow you to be about 15 feet above the housebracket but the stated
loads are bigger so they don't provide a direct answer.
