ABSTRACT:
Support structure for a paraboloid reflector of electromagnetic radiation. The structure comprises a plurality of abutting flat ribs arranged on edge in rotated concentric square patterns, with the ends of inner ribs meeting the sides of adjacent outer squares at forty-five-degree angles. The concave parabolic forward edges of the ribs are aligned at their junctures, establishing the curve of a screen reflector. Corner gussets are positioned on parallel planes that are perpendicular to the focal axis of the paraboloid. The structure is assembled by inserting fasteners through matching holes in the ribs and corner gussets.
