ABSTRACT:
Earth station antenna and method for assembly wherein the antenna has a frame made up of accurately stamped radial ribs and circularly disposed cross members, the frame being filled in by either sheet metal segments or by screen mesh segments to form a parabolic surface. The ribs are supported by a central ring or barrel, which is rotatable during assembly, and by back braces which are adjustable to bring the ribs to true parabolic positions and to tune the completed antenna. Assembly may be done from the ground by rotation of the central barrel. Novel connection means and a positioning gage are used during assembly of the antenna.
