2. Description of the Related Art In recent years, broadcasting satellites (BS) and communication satellites (C)
Antennas that directly receive radio waves from S) have become popular. Especially with the miniaturization of the antenna, not only the dedicated support (mast) but also the VHF,
It has been demanded that the antenna can be easily arranged in the middle part of the pillar of the UHF TV antenna, the handrail of the balcony of the building, the window of the room, and the like.

FIG. 12 shows a first conventional example of a mounting device for a center feed type satellite broadcasting receiving antenna having directivity in the normal direction of the antenna body. Here, 1 is a center-feed type satellite broadcast receiving antenna, for example, having a structure of a planar antenna in which a plurality of radiating elements are arranged in a plane, and having directivity in a normal direction of a plane in which the radiating elements are arranged. There is. A mounting base 67 is provided on the rear side of the antenna 1.
And a converter 6 are provided. A metal attachment part 68 is attached to the attachment pedestal 67 of the antenna 1 by a pin 69 provided at one end of the attachment part 68.
A column-shaped cylindrical portion for supporting columns, which is formed at the other end portion of the column 8 and has a sleeve shape, is fitted into the supporting column 20. Then, after the support mounting tubular portion of the mounting component 68 is fitted and inserted from the upper end of the support, the screw 71 that is screwed into the support mounting tubular portion is tightened until it comes into contact with the support outer circumference. Installation is done. In the center feed type antenna, the directional beam is in the normal direction of the antenna body,
In FIG. 12, the elevation angle is indicated by θ.

FIG. 13 shows a second conventional example of a device for mounting a satellite broadcast receiving antenna, and shows a structure in which the structure having the mounting parts 68 shown in the first conventional example is mounted to the middle portion of the column 20. Shows. This is because when the elevation angle of the center feed type antenna 1 becomes large (for example, when used in Okinawa area in Japanese satellite broadcasting), the upper end of the antenna 1 and the support column 20 contact each other in the first conventional example of FIG. Therefore, in order to provide a necessary distance between the upper end of the antenna 1 and the support 20, a separate L-shaped intermediate mounting component 75 is prepared as shown in FIG.
, And the antenna 1 is attached via the intermediate attachment separate component 75. In the intermediate mounting separate component 75, a pillar-shaped tubular portion for pillar mounting 76, which is sleeve-shaped for being fitted into the pillar 20, is fitted and inserted from the upper end of the pillar 20, and the cylinder is placed at an arbitrary position in the middle portion of the pillar 20. The intermediate attachment separate component 75 is attached to the intermediate portion of the column 20 by tightening the screw 72 screwed into the cylindrical portion 76 until it abuts on the outer periphery of the column inside the cylindrical portion for column attachment 76. Then, the antenna 1 is mounted by fitting the support mounting tubular portion of the mounting component 68 into the upper end portion of the L-shaped intermediate mounting component 75 and fixing it using the screw 71.

[0006]

By the way, in the center feed type satellite broadcast receiving antenna mounting apparatus shown in the first to third conventional examples, the mounting base 67 is provided on the rear side of the antenna 1 and the mounting is performed. The basic structure is that the mounting parts 68 are attached to the mounting base 67, but since the mounting parts 68 have no special measures, the following inconveniences and problems occur depending on the mounting position of the antenna.

When the antenna is mounted on the middle part of the pillar of the VHF television antenna, the handrail of the veranda, etc., in the region where the elevation angle of the antenna is large, the mounting part 68 alone as in the first conventional example is used for the antenna 1. The upper end is a post 2
Since it comes into contact with 0 and cannot be attached, the separate component 75 for intermediate attachment is required as shown in the second conventional example, and the number of components increases and the labor of attachment becomes complicated. When the antenna 1 is received by a window in a room, as shown in the third conventional example, a stand 7 having a pillar portion as a separate component.
8 is required. In this case as well, the number of components is increased, and the stand with columns is expensive.

Further, by using the indoor installation stand 40 described in the third installation example of the first embodiment, indoor installation is possible, and the same operational effect as the above-described third installation example can be obtained.

According to the above-described first and second embodiments, when the satellite broadcast receiving antenna is installed on an outdoor pole or the like, the pole mounting cylindrical portion 10 is formed by fitting the mounting arm 8 and the semi-arcuate mounting component 9. 1 is also formed in the middle part of the column.
It can be mounted without using the separate component for intermediate mounting shown in the second conventional example of No. 3. Further, when installing indoors, it is not necessary to use the large stand with a pillar shown in the conventional example of FIG. 14, and a simple structure and inexpensive indoor installation stand 40 are simply attached to the mounting arm 8. Can be attached to.

Although the embodiment of the present invention has been described above, it is obvious to those skilled in the art that the present invention is not limited to this and various modifications and changes can be made within the scope of the claims. Let's do it.

[0033]

As described above, according to the satellite broadcast receiving antenna mounting apparatus of the present invention, the length of the mounting arm rotatably provided on the satellite broadcast receiving antenna is set to the maximum elevation angle of the satellite broadcast receiving antenna. Since the support pillar or the extension line of the support pillar is sometimes set so as not to come into contact with the upper end portion of the satellite broadcast receiving antenna, it is possible to deal with the area where the elevation angle of the antenna is large without preparing a separate part. Further, even when installed indoors, an indoor installation stand, which has a simple structure and is inexpensive, can be easily installed without using additional parts.
