Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mounting base for an antenna for receiving SHF broadcasting.

[Conventional technology]

When receiving SHF broadcasts on the ground, it is necessary to adjust both the horizontal angle and the elevation angle so that the antenna faces directly toward the broadcasting satellite. Therefore, an antenna mount that combines a horizontal movable part for horizontal angle adjustment and a vertical movable part for elevation angle adjustment has been proposed.

For example, in the one shown in FIG. 6, a horizontal movable part 43 having a level (not shown) is provided on a base 42 to which extendable legs 41 are attached, and a vertical movable part 44 is attached to this horizontal movable part 43. . This vertically movable part 4
Attach the offset parabolic antenna 24 to the antenna 4 and rotate the vertically movable part 44 in the vertical direction to obtain a previously calculated elevation angle (the angle between the radio wave arrival direction and the horizontal plane) at the receiving point, for example, 25°. The pointer of the vertical movable part 44 was aligned with 25 degrees of the elevation angle scale of the horizontal movable part 43, which was kept horizontally.

[Problem that the invention attempts to solve]

However, in order to set an antenna other than the offset parabolic antenna, such as the parabolic antenna 25, at the same elevation angle of 25 degrees as the offset parabolic antenna using the antenna mounting base shown in FIG. Since it is parallel to a plane 47 including the edge, it is necessary to interpose an angle correction adapter 46 having a predetermined angle between the mounting surface 45 and the vertically movable portion 44, as shown in FIG.

Therefore, it is necessary to prepare as many conventional antenna mounting stands as there are types of antennas, or to prepare angle correction adapters as described above for each type of antenna. However, it is extremely uneconomical to prepare a large number of antenna mounting bases or a large number of angle correction adapters, and the selection and installation work of angle correction adapters is complicated. Another drawback is that it takes time.

The present invention has been made in view of the above points, and the object is to provide a compact antenna mounting base that can be easily and accurately set without an insert such as an angle correction adapter even when the types of antennas are different. .

[Means for solving problems]

The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 5, which correspond to embodiments. A horizontal horizontal axis 6 is provided on the horizontally movable part 3 which is horizontally rotatably mounted on a horizontally arranged support base 1, and a first elevation angle having an antenna mounting surface parallel to the horizontal axis on the axis of this horizontal axis. The adjustment movable part 14 and the second elevation angle adjustment movable part 11 are attached so that they can rotate independently of each other, and the first elevation adjustment movable part 1
4 and the second elevation adjustment movable part 11, a pointer 28 is attached to the other, and an antenna selection scale 27 facing the pointer 28 is attached to one of the second elevation adjustment movable part 11 and the horizontal movable part 3. A pointer 29 is attached to one side, and an antenna elevation angle scale 30 facing the pointer 29 is attached to the other side, and the movable parts 3, 11, and 14 can be set at required rotation angle positions.

[Effect]

To set the antenna on the antenna mount,
First, the inclination of the support stand 1 oriented in a predetermined direction is adjusted so that the horizontal movable part 3 attached thereto becomes horizontal. Then, the first
Rotate the elevation adjustment movable part 14 up and down, align the pointer 28 with the scale corresponding to the antenna to be attached in the antenna selection scale 27, and move the movable part 14 to the movable part 11.
Set to . Next, the second elevation adjustment movable part 11 is rotated up and down with respect to the horizontal movable part 3, the pointer 29 is aligned with the scale corresponding to the elevation angle at the receiving point on the antenna elevation angle scale 30, and the movable part 11 is set in the movable part 3. . When the elevation angle setting of the antenna is completed in this way, the horizontal angle of the horizontally movable part 3 is adjusted so that the antenna faces directly toward the broadcasting satellite.

Next, in order to attach an antenna of a different type to the antenna mount, since the elevation angle at the reception point is constant regardless of the type of antenna, rotate the movable part 14 relative to the movable part 11 and mark the antenna selection scale. After setting the movable part 14 to the movable part 11 by aligning the pointer 28 with the scale corresponding to the antenna to be attached in 27, the old and new antennas can be replaced.

Note that the antenna is attached to the first elevation adjustment movable part 14 in advance.
The device may be operated after being attached to the attachment seat 18, or it may be attached to the attachment seat 18 during the operation process.
