This is one of my favorite questions to answer on TT. The best
compilation of tower-related practice was created by N1LO:
http://www.qsl.net/n1lo/tower_ref.pdf . Steve K7LXC also recently published
a book on tower practices. Check out his web pages:
As for other self-supporting towers to consider, take a look at the
Trylon Titan series. You can find a full description on Steve's site. I
built (literally from the ground up) a T-500 in 2001. The max height
available with this model is 72 feet. It's a true medium-duty tower; I
suggest you check out the full loading capability of whatever tower you
select vs the antenna loads you intend to install on it. You can also
select Trylon's T-600 series - it's a bit beefier but the maximum height is
64 feet (one section less than the T-500 series.)
Pouring all the concrete at one time is a good idea. The mixer truck
will mess up your yard only once.
