As disclosed in JP-A-259603, a method of increasing the range of expansion and contraction length of the elevation angle adjusting jack has been used. In the case where the elevation angle adjusting jack is not used, as disclosed in JP-A-62-164303 and Japanese Utility Model Laid-Open No. 4-75412, it is rotated and fixed about an axis that supports the reflecting mirror. Alternatively, a method has been used in which the upper end of the reflecting mirror is configured to be rotatable and the arm provided at the lower end is moved to adjust the elevation angle.

た。For example, in a parabolic antenna having an elevation angle drive range of 0 ° to 20 °, the movable range of the elevation angle adjustment jack corresponds to the elevation angle drive range of 0 ° to 20 °. The elevation angle of the parabolic antenna is 0 ° when the length of the jack is minimum, and the elevation angle of the parabolic antenna is 20 ° when the length of the jack is maximum. Therefore, with such a conventional structure, it is impossible to expand the elevation angle drive range unless it is replaced with an elevation angle adjustment jack having a large movable range.
