Another thing to consider when it comes to tower height is feedline loss,
especially on UHF and up.  On top of a really good hill, it might make more 
sense to have a 35' tower with good feedline than a 100' tower where you
feel compelled to add preamps, mount the transverters in a box on the tower,
