The cost of 999 plus a controller is about the same as ring or close
isn't it? You get 360 rotation and what appears to me to be a balanced
load around the entire tower.
Many sidemounts I have seen have a bearing or something up higher to
remove some of the down force. How much weight and antenna can 25g
handle like that?
