I have an UST HDX-772MDPL (spec 700lbs, 70sq ft @ 70mph) with a SteppIR MonstIR
and F12 Sigma-280 Magnum mounted, so yes UST does have additional towers
available based on HDX-5106 design. Steve Morris K7LXC performed the magic for
my successful tower and antenna installation--thanks Steve.

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.
