[TowerTalk] Tower for a DB36

[Grant Saviers]

I think the base (concrete) drawings are on the UST web site, so they 
are a good proxy for same height tower carrying capacity, assuming of 
course the engineers all used the same UBC and safety factors. YMMV.

The UST towers are available in "super sized" versions - an HDX689 (89') 
uses the bottom sections of an HDX5106 (106') and in theory both a 
HDX672 and  HDX772 (72') exist which use, respectively, the bottom 
sections of an HDX589 (89') and HDX5106 (106').  However, prices go up 
pretty steeply - and HDX589 costs a little more than one half of an 
HDX689.  The HDX689 was on the Texas Towers price list but it is not 
there now.

When you call UST ask for Becky, she is very helpful.
