PROBLEM TO BE SOLVED: To reduce the number of parts and to facilitate direction adjustment by constituting of a mount fitting tool fitting an antenna and a mast fitting tool connected to the mount fitting tool and adjusting the azimuth angle of the antenna by means of the mount fitting tool for the mast fitting tool on a mast. SOLUTION: A mast fitting tool 1 fitting a parabolic reflecting mirror 8 and a mast fitting tool 3 which is installed on a mast 2 and is connected to the mast fitting tool 1 constitute the antenna fitting tool. At the time of adjusting the azimuth angle of the parabolic reflecting mirror 8, the mast fitting tool 1 is turned around the mast 2 and the azimuth angle is roughly adjusted and finely adjusted. Then, bolts 10 and 10' are fastened after adjustment. For adjusting the azimuth angle, the azimuth angle of the parabolic reflecting mirror 8 can considerably easily and precisely be changed. For adjusting an elevation angle, bolts 20 and 20' are loosened, an operation for turning the tool to the desired elevation angle is easy and the elevation angle can precisely be adjusted.
