I have had an 80ft Heights Al tower up since 1976, and I bought it 
used back then! TH-11 on top. The first three sections might be 
unique in that the tubing is 0.25inch wall thickness. I originally 
installed it self supporting. During a once-per-hundred-years 
blizzard in1978 it was waving around like a mobile whip. So I added 
two sets of phillystran guys. They are not under much tension to 
limit down force on the tower; just limit the sway. This is because I 
have always been told that Al can not stand compression loads like steel.
