I understand that rotators are not designed to handle lateral loads, and
that I should therefore have the rotator on one shelf, then a second shelf
above that with a radial support bearing on it, to handle the lateral loads.
The most likely antenna at the moment (still a moving target) weighs 29kg,
with a 7.2 sq ft wind load and a 6m turning radius. Kurt K7NV suggested
welding two plates on the side of my pole/tower, at the top, a few feet
apart. Does anyone know of existing designs/drawings for that kind of thing?
