Abstract
A non-furlable paraboloidal radio frequency reflector (10) is formed of a mesh-like flexible reflective surface (18) supported by a central hub (12) and a peripheral rim (14). The hub and rim are interconnected by flexible spoke-like structural cables (16, 24) acting in tension to establish the desired spatial relationship. Reflector surface-positioning cables (20, 26) are secured at their ends to the hub, rim or structural cables and are further secured to the reflector surface at points of intersection (22) therewith intermediate their ends to thereby establish an approximation of the desired curved shape of the reflector surface.
