So you want to install the whole 200 foot tower in one piece? This sounds pretty dangerous to me as Rohn 55G is not that strong. John KK9A I am going to assemble a 200 foot Rohn 55G tower on the grou

GAC3455 anchor rods are not that heavy. If it were me, I would just bend the rod to the correct position by pushing on it. Also the anchor rods should be less than 45 degrees, more likely 41 degrees.
