IMHO, IF the tower base was installed correctly, the legs should be able to weep moisture into the required gravel underneath the legs and into the ground thereafter. The tower obviously has some sor

The issue is not the weight of the antenna, but the surface area it presents to the wind. Rohn's data on bracketed towers is pretty sparse. They show one example with a bracket at 66' on a 90' tower

"Three feet of the tower are buried in a cubic yard of concrete down two feet from ground level." My concern would be corrosion fatigue at the base. You didn't state the soil condition, but assuming
