PROBLEM TO BE SOLVED: To provide a structure and assembly method of an antenna system in which a position and an attitude of a primary radiator can be accurately controlled. SOLUTION: The antenna system is equipped with a parabolic reflector 1, the primary radiator installed at a focal position F of the parabolic reflector 1, and a support mechanism 40 for supporting the primary radiator in the predetermined position and attitude with respect to the parabolic reflector 1, and the support mechanism 40 is provided with a structure for mounting a light source at the position where the primary radiator is installed, to emit a light beam along with the central axis of the primary radiator. The mount structure is equipped with a dummy 25 that has the same outer form as the primary radiator and can be mounted at the position, where the primary radiator is installed, in the support mechanism 40 and the light source is mounted onto the dummy 25 in the same direction as the primary radiator.
