PURPOSE:To adjust the angle of a reflector easily and to prevent the reflector from the concentration of stress by pivoting a part of the refelctor to a supporter and fitting the other part to the supporter through a link. CONSTITUTION:The reflector 10 for a parabolic antenna has plural ribs 12, 14, 16, 18 at its back and is fitted to the supporter 20 through upper and lower supporting tools 22, 24. A clamp 26 of the upper supporting tool 22 is fitted to the upper end part of the supporter with a bolt 28 and a nut 30 and a blacket 32 is projected from a part of the upper supporting tool 22. Blackets 36, 38 are pivoted through a pin 34 and fixed to a center rib 14 of the reflctor 10. One end of the rink 52 is pivoted to a clamp 46 of the lower supporting tool 24 through a pin 50 and the other end is pivoted to a blacket 56 and fixded to a parallel rib 18. Since the lower supporting tool 24 can be vertically moved along the supporter 20, the angle of the reflector 10 can be easily adjusted. |
