Abstract
An unfurlable antenna reflector comprises a rigid central truss (12) on which are pivotally mounted circumferentially spaced booms (18). A network of tensioning cables (24) interconnect the ends of the booms to define a reflector-supporting net when the booms are in their fully deployed position. The booms deploy sequentially, to minimize shock loading, and have lengthening means (22) which simultaneously extend the outer ends of the booms after all the booms have reached their deployed position. A flexible mesh-like reflector surface (20) is connected to the net and is formed into a predetermined non-planar shape by net-shaping secondary cables (30).
