The PE sheets that were sent for my yet-to-be-delivered US Towers HDX-555
have increased the hole size to 5'x5'x6.5' and larger rebar (the website
says 4'x4'x6'). When I asked what the windload rating would be for 105mph
(here in Florida) I was told by the very nice lady that the PE said it
could handle "2 sq ft of antenna." Wow, it went from 30 sq ft at 70mph to
2 sq ft at 105mph. Of course, what I really needed to know is what it would
handle cranked all the way down, since I surely won't leave it up in the
face of an approaching hurricane. She said the PE wanted $450 to tell me
that info. Now I realize that's probably money well spent, but the $900
shipping and $600 for concrete has already drained the well, so to speak.
:-) I can already see the look in my wife's eyes - she's planning how
she's going to get even with me!
