Claims

[Scope of claim for utility model registration] An arm with an antenna element attached to the mast. A mounting base member and a holding member for mounting in a cross-shaped manner are tightened using bolts and tighteners such as wing screws, and the mounting base member is bent to have a U-shaped cross section, The arm is held within the member, and both ends of a bolt inserted into the mounting base member are inserted into the elongated insertion hole formed in the holding member and tightened with the tightener. A cutout opening is formed in one of the elongated insertion holes for releasing the engagement with the bolt, and a cross-shaped insertion hole is formed at the bent corner of the mounting base member; Insert the tip of the tightening bolt whose base end is locked to the arm into the cross-shaped insertion hole, and leave the tightener, such as a butterfly screw, screwed to the tip of the bolt in its attached state. An antenna characterized in that the direction in which the arm is attached and detached can be changed and set, and the direction in which the antenna element is disposed in the arm fixed to the mast can be fixed in any receiving state. Crotch arm tightening mechanism.
