PURPOSE:To adjust the elevation of a radio wave reflector properly according to its installation place by fixing the rack side end part of a lateral frame for wave collector attachement in a lengthwise movable state. CONSTITUTION:The radio wave reflector 1 is rotatable within a specific angle range by fixing both center side edge parts and the upper end part of a semiarcuate supporting frame 4 fixed to a rack 3 pivotally with screws 5. The reflector 1 is fitted with the lateral frame 6 for fitting a wave collector 2 and a longitudinal frame 7, and the frame 6 is bridged by fixing both ends to side edge parts of the reflector 1 with screws 8. The frame 7, on the other hand, is fixed to the center part of the frame 6 piercing its one end part, and the other end part 7' is fixed to the lower edge part of the reflector 1 with a screw 9 to hold the wave collector 2 and reflector 1 at constant relative positions while preventing the reflector 1 from deforming owing to wind pressure, etc. Then, the hole 10 of the end part 7' for the screw 9 is sized long and the frame 7 is fixed to the rack 3 or frame 4 so that it moves lengthwise. |
