Nathaniel:
I would second Joe Subich K4IK's recommendation against unguyed Rohn
tower at that height and recommending the Trylon self-supporting tower
series. I'm in the process of putting up a 64-foot Trylon in my small back
yard. Check out www.qth.com/KA9FOX and www.qsl.net/n8wrl/index.htm
for photo records of typical installations. Also check out
www.championradio.com for pricing info on the Trylons. But you'll need to
know wind information about your location, which will help you decide which
model Trylon tower to buy (assuming you go that way.) Champion Radio also
has a page on wind speed listed by US counties.
Good luck and let us know how you decide to proceed.
