Abstract: A portable foldable support assembly for a microwave dish antenna in which three or more legs are hinged to a vertical center post near its upper end to engage the ground plane beyond the center of gravity of the antenna, and a torsional stabilizer secured to the lower end of the post having three or more moment arms respectively disposed circumferentially between adjacent pairs of legs and in which a pair of tension members couple the lower end of each leg to two adjacent moment arms on opposite sides of the central axis to resist rotation of the post in either direction.
