In FIG. 3, a mirror 16 with a target engraved on it is attached to the reference hole 10 of the sub-reflector 15, and the mirror 16 of the sub-reflector 15 is viewed with an optical collimator 17 set on the mirror axis of the main reflector. In this method, the inclination and eccentricity are adjusted, and the height is measured using a tape measure. This method requires skill in handling and adjusting the optical collimators, and has the problem that it takes a long time to adjust each collimator separately and gradually adjust it.

提供することにある。 Furthermore, in FIG.
In this method, the height and eccentricity are determined using a jig 18, and the inclination is adjusted using a dial gauge 19. This adjustment is performed by rotating the dial gauge 19 on the circumference of the sub-reflector reflecting surface.
Tilt the sub-reflector 15 so that the readings of 9 are the same,
Since it is necessary to repeat the adjustment many times, this also has the problem of increasing the adjustment time. An object of the present invention is to solve these problems and provide an antenna sub-reflector that is easy to handle and requires less time for installation and adjustment.
