 hi Kevin,

I highly recommend Universal Tower. Their tower sections are very well and 
precisely made, which is important in case you want to alter your setup later.

My own 85' aluminum tower is a mix of (old) Heights Tower parts and 2 new 
sections from Universal. I will not recommend you to follow my example but buy 
everything new from Universal. The big advantage with an aluminum tower is that 
it's light, mine is total #300. We were two people setting it up. It was raised 
with a falling derrick. 

Through a genius engineering alteration I have four guy wires added which 
increased the wind resistance from 85 to 125 mph. I have the calculations 
somewhere but am not sure where so, please, don't ask me to dig them up. I can 
give you the resulting design, though.

My only concern with an aluminum tower is that it is very springy compared to a 
steel tower, something you will notice when you climb it. I will NOT recommend 
you to put up a tower using only section the size of a Rohn 25. Aluminum is not 
as strong as steel. Follow the recommendations from Universal. They have 
several ready designed towers for various heights on their web site.

God luck with your tower projects and 73,

Hans - N2JFS
