PURPOSE:To adjust easily and accurately in azimuth angle of installation of a parabola reflection mirror by providing a minute adjusting means of the azimuth angle. CONSTITUTION:A horizontal base 14 is fixed to the upper end of an outer cylinder screwed to a mast. An adjusting plate 1 mounting the parabola reflection mirror is placed turnably onto the base 14. Then, the tip of a handle 24 supported to the adjusting plate 1 is fitted to plural positions of an outer circumferential face 16 of the base and screwed to an adjusting nut 20 held turnably. That is, the azimuth angle is decided by turning the adjusting plate 1 mounting the parabola reflection mirror on the fixed base 14. Then, the azimuth angle is adjusted minutely by screwing the adjusting nut 20 held to the outer circumferential face 16 of the base with the handle 24 supported to the adjusting plate 1. Thus, the azimuth angle of installation of the parabola reflection mirror is adjusted easily and accurately. |
