An embodiment of the invention generally relates to an apparatus for deploying a segmented reflector antenna. The apparatus includes a plurality of segments that can be rigid or flexible where each segment is hinged to an adjacent segment on either longitudinal side. The apparatus also includes a base, a plurality of inner deployment beams, and a plurality of outer deployment beams. Each inner deployment beam connects an inner side of a respective segment to the base and having a folded position and an extended position. Each outer deployment beam connects an outside side of a respective segment to the base and has a folded position and an extended position. The plurality of segments in a hinged folded position in response to the plurality of inner deployment beams being in the folded position and the outer deployment beams being in the folded position.
