Rob - I just went up with 60' of Rohn 55G. I still have a 68' Rohn 25G with
foldover, but just think that it is too small especially considering we are
30 miles from the Gulf of Mexico. The 55g (with the base section as per
their recommendation) is hell for stout compared to the 25G. A very
noticeable difference based on the size and strength.
I can send photos of the base and tower if you like.
