The present invention relates to a support structure, system and materials for supporting a reflector. A rim stiffening beam is securely attached to the circumference of the reflector. A plurality of support struts is attached to the rim stiffening beam, joining to one or more nodes, thereby providing support for the reflector and substantial open volume directly behind the reflector for instrumentation, drive and control units, or other purposes. A central support structure supports the nodes and further supports a plate attached to the back of said reflector. This plate is advantageously relatively stiff in its radial dimension but relatively flexible in its axial dimension.
