Problem with the rhon towers is they are not made to free stand over 30 
feet or so.  Above that they need many guys.  You also have to take a 
look at wind load.  I wouldn't trust 30 foot of rhon to free stand with 
large tri bander and other antennas.  They're not designed to free 
stand.  I don't recall the specs on rhon 45, but I remember for 25, 30 
feet is the absolute max they recommend.
