Blake,
  I have seen the ratings that are on Champion Radio site. They are
incorrect for some counties. I know this because I had to get my tower
rated at 140 m.p.h. @ 3 second gust and exposure "C". They need to
update their site. This is for Dade, Broward, and some other counties as
well.

                                   N4JRZ

No, it's 115.

I put 110 since my Rohn book doesn't go any higher.
