ンテナ反射鏡。 A box-shaped truss structure that forms a paraboloid of revolution as a whole by combining a large number of beams of constant length and the ends of the beams, and is supported at each beam connection point inside the truss structure. The truss structure comprises a truss antenna reflector comprising a metal mesh forming a paraboloid of revolution along the truss structure, and a feeding horn that blows radio waves using the metal mesh surface as a radio wave reflection surface. A truss antenna reflector characterized in that a beam of variable length is arranged in addition to a beam of constant length.
