A compactly stowable and deployable support architecture, such as may be used for supporting an energy directing surface, includes radial and hoop support members including upwardly and downwardly extending strut members for deploying a surface, such as a mesh-configured antenna reflector. In one aspect, at least one strut is formed as a telescoping tube member. A multi-sided foldable hoop structure has a plurality of foldable joints, and generally radial struts that extend from and are foldable about corner joints of the hoop structure. At least one drive mechanism is coupled to torque tubes that drive geared hinges of the multi-sided hoop structure. The hinges and drive linkages are geared to synchronously unfold the multi-sided foldable hoop structure and the radial struts, so that the antenna surface may be smoothly deployed from its stowed condition.
