<p><P>PROBLEM TO BE SOLVED: To provide an antenna which has high assembling work efficiency with a simple configuration. <P>SOLUTION: This antenna device includes a mounting angle constituted of an antenna support rod mounting part having a mounting means for being mounted on an antenna support rod, which has a shape that corresponds to at least a half in the circumferential direction of the antenna support rod formed so as to be almost parallel with the axial line of the antenna support rod at the front side of the reflector or to the outer circumferential surface of an area narrower than the half, and a reflector mounting part provided continuously so as to be almost orthogonal to the projection direction of the mounting part at the rear side of the mounting part to be mounted to the reflector, at almost the center part of a front side of reflector 20. The antenna support rod mounting part of the mounting angle is attached to a peripheral surface from the circumferential direction of the antenna support rod, and is firmly fixed to the mounting means by a fixing means. When the reflector is mounted on the antenna support rod, the mounting means is positioned, and an opening end at the rear end side of the antenna support rod is blocked up by the reflector or a portion of a member constituting the mounting angle. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
