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 horizontally movable part 53 having a level (not shown) is provided on a base 52 to which telescopic legs 51 are attached, and a vertically movable part 54 is attached to this horizontally movable part 53. . This vertically movable part 5
Attach the offset parabolic antenna 32 to the receiver point 4, and rotate the vertical movable part 54 in the vertical direction to obtain an elevation angle of 25 degrees (the angle between the radio wave arrival direction and the horizontal plane) at the reception point calculated in advance. The pointer of the vertical movable part 54 was aligned with 25 degrees of the elevation angle scale of the horizontal movable part 53, which was kept horizontal.

[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 33, at the same elevation angle of 25 degrees as the offset parabolic antenna 32 using the antenna mounting base shown in FIG. Since it is parallel to a plane 57 including the end edge, it is necessary to interpose an angle correction adapter 56 having a predetermined angle between the mounting surface 55 and the vertically movable portion 54, 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 was devised in view of the above points, and is a compact and inexpensive antenna mount that can be easily and accurately set without inserts such as angle correction adapters even when the type of antenna is different due to its simple configuration. The purpose is to provide.

[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 movable part 3 mounted so as to be horizontally rotatable on a horizontally arranged support base 1 is provided with a horizontal horizontal axis 7, and the horizontal axis 7 has an antenna mounting surface parallel to the horizontal axis. 12 is rotatably attached, and a ring-shaped display plate 2 is rotatable on the horizontal axis axis with respect to the elevation adjustment movable part 12 and the horizontal axis 7.
4 is disposed in front of the movable part 12 for adjusting the elevation angle, and a pointer 28 and an antenna selection scale 25 are arranged on either the inner circumferential surface or the outer circumferential surface of this display board 24 as a border.
The pointer 27 and the antenna elevation angle scale 26 are made to face each other with the other peripheral surface as a boundary, and the display board 24 is placed between the scale of the antenna selection scale 25 and the pointer 2.
The movable part 1 for adjusting the elevation angle can be attached to and detached from the movable part 12 for adjusting the elevation angle at the position where the movable part 8 for adjusting the elevation angle matches.
2 to the horizontal movable part 3, and a clamp mechanism for fixing the horizontal movable part 3 to the support base 1.

[Effect]

To set the antenna on the antenna mount,
First, the inclination of the support base 1 oriented in a predetermined direction is adjusted so that the horizontal movable part 3 attached thereto becomes horizontal. When the adjustment is completed, the movable part 12 for adjusting the elevation angle and the display board 24 are uncoupled, the display board 24 is turned, the pointer 28 is aligned with the scale corresponding to the antenna to be installed in the antenna selection scale 25, and the display board 24 is moved again. Attach to section 12. Here, the clamp between the movable part 12 for adjusting the elevation angle and the movable part 3 for horizontally adjusting the elevation angle is released, and the movable part 12 for adjusting the elevation angle is turned so that the pointer 27 is aligned with the scale corresponding to the elevation angle at the reception point in the antenna elevation angle scale 26, and the movable part 12 is rotated. is clamped to the horizontal movable part 3. When the elevation angle setting of the antenna is completed in this manner, the clamp between the horizontally movable part 3 and the support base 1 is released, and 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 receiving point is constant regardless of the type of antenna, turn the display plate 24 to mark the antenna selection scale 25.
Align the pointer with the scale corresponding to the antenna to be installed inside and set it, then replace the old and new antennas.

The antenna may be attached to the movable part 12 for adjusting the elevation angle before operation, or may be attached to the movable part 12 during the operation process.

[Effect of idea]

As explained above, according to the present invention, different types of antennas can be set at different positions depending on the type using a single antenna mount equipped with an antenna selection scale and an elevation angle scale, and can be set at a common predetermined elevation angle (elevation angle at the receiving site). This eliminates the need to prepare as many antenna mounts or angle correction adapters as there are antenna types, making it truly economical and easy to replace with different types of antennas on the antenna selection scale. Since it is only necessary to change the scale, antenna replacement can be done extremely easily and accurately. Furthermore, since the structure is extremely simple, such as attaching a display plate to a combination of an elevation adjustment movable part and a horizontal movable part, there is an advantage that a compact and inexpensive antenna mounting base can be provided.
