するパラボラアンテナの仰角調整機構。 A fan plate for adjusting the elevation angle attached to the back surface of the spherical reflector, a bolt for an elevation fulcrum that is movably inserted above the fan plate and whose tip is fixed to a support pole, and the fan plate for the elevation angle adjustment. In the elevation angle adjustment mechanism for a parabolic antenna, the elevation angle adjustment mechanism for a parabolic antenna includes an elevation angle adjustment bolt inserted into a circular arc-shaped elongated hole that regulates the elevation angle of the reflector downward and whose tip is fixed to the support pole, the elevation fulcrum of the fan plate; The insertion hole of the bolt is composed of an upwardly inclined elongated hole, and the width of the arcuate elongated hole perpendicular to the longitudinal direction is at least a length corresponding to the height of both ends of the insertion hole. A distinctive feature is the elevation angle adjustment mechanism of the parabolic antenna.
