First, it is the mounting position of the fixing means 40. In this different embodiment, the fixing means 40 is mounted on the holding piece 55 side. That is, a through hole 54b is formed in the engaging portion 54 of the sandwiching piece 55 in place of the cutout portion 54a, and the fixing means 40 is freely inserted into the through hole 54b. On the other hand, an L-shaped notch 34b is formed in the mounting portion 34 of the abutting piece 35 so as to have an opening 34c at the upper end of the mounting portion 34a instead of the through hole 34a.
The fixing procedure according to this configuration is performed as follows. If the antenna mast 101 is pinched, first, the pinching tool 30 is brought into a temporarily fixed state which is the first state. Then, the bolt head 45 side of the bolt 41 is inserted from the opening 34c of the L-shaped notch 34b, and the wing nut 41 is screwed while the bolt 41 is housed in the innermost part 34d of the L-shaped notch 34b. It is done by combining. In this embodiment, the bolt 41 can be arranged so as to protrude largely outward from the engaging portion 54, and the fixing means 40 does not get in the way when the antenna mast 101 is inserted into the clip tool 30. In the figure, 34e is a protrusion for preventing the bolt 41 from coming off.

Thus, the engaging piece 54 side of the sandwiching piece 55 is opened, and the antenna mast 101 and the veranda 102 can be easily and quickly attached to the distal end portion or the intermediate portion. Further, when the pressing on the knob 51 is stopped, the clip 30 is closed at one end side by the urging force of the ridge 70, and the antenna mounting bracket 1 can be rotated in a temporarily fixed state with respect to the antenna mast 101 and the veranda 102. Can be fixed. In other words, since the antenna mounting bracket 1 can be temporarily fixed to the antenna mast 101 or the veranda 102 so as to be rotatable, for example, in the direction adjustment of the antenna 2 or the like, the field strength measuring instrument or the like is operated without supporting the antenna. Since it is possible to concentrate on the adjustment work, the direction can be adjusted very easily.
Furthermore, the fact that the antenna mast 101 and the veranda 102 can be temporarily fixed can be considered to have the following effects on the transition to terrestrial digital broadcast reception. That is, the antenna mounting bracket according to the embodiment of the present invention is an antenna that needs to check not only the reception level but also the quality of received radio waves coming from various directions, such as an antenna for receiving terrestrial digital broadcast waves. If it is used, the confirmation work of the received radio wave quality in other directions can be performed easily and quickly, and the direction can be adjusted in the optimum direction in a short time.
Moreover, since the antenna mast and the veranda can be easily attached to the support, the antenna installation work at a high place can be performed safely. Further, in the embodiment of attaching to the veranda, it is possible to perform a safe attaching operation because the person does not lean out to the outside of the veranda.
Further, when the antenna direction adjustment is completed, it is possible to easily attach firmly to a support such as an antenna mast or a veranda by holding the holding tool with the fixing means.
Further, in the embodiment of attaching to the veranda, the pinching tool does not protrude greatly inside the veranda, and the fixing means does not protrude inside the veranda. It is possible to provide an antenna mounting bracket with a low risk of using tools.
