Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting device for a satellite broadcast receiving antenna and the like, and relates to a mounting device provided with an azimuth magnet for facilitating a general adjustment of the azimuth angle of the antenna when mounting the antenna.

[0002]

[Prior art]

 It is necessary to set the parabolic antenna for satellite broadcasting reception so that the receiving surface is correctly oriented to the broadcasting satellite. This is because the radio waves received are weak radio waves from broadcasting satellites far away on the earth, so if the direction of the receiving surface of the parabolic antenna is misaligned, satellite broadcasting reception may become almost impossible. Is. For this reason, a table showing the azimuth angle and elevation angle for each area and satellite is usually attached to such an antenna device. Rough adjustments are made to point in the direction, and after that, fine adjustments such as azimuth and elevation are made according to the signal output from the receiver according to the signal received by this antenna. During this rough adjustment, the elevation angle can be set, for example, by looking at the scale for elevation angle adjustment provided on the antenna device, but it is difficult to set the azimuth angle without using a direction magnet or the like. is there.

[Problems to be solved by the device]

 In view of such a point, the present invention attaches an azimuth magnet to the mounting base of the parabolic antenna, and at the time of setting the parabolic antenna, knowing the azimuth with this azimuth magnet enables easy general adjustment of the azimuth angle. Especially.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a columnar mast which is erected substantially vertically, a rotatable mast mount is mounted on the upper part, and a parabolic antenna whose elevation angle can be adjusted is mounted on the mast mount. The present invention provides an antenna mounting device characterized in that a directional magnet having a rotation axis of a mast mount as a center of rotation is mounted on a substantially horizontal surface of an upper portion of the mast mount.

[0005]

[Action]

 With the above-described configuration, in the antenna mounting device according to the present invention, the parabolic antenna is mounted on the mast mount, and the mast mount is capped on the upper portion of the column-shaped mast which is erected substantially vertically. It The azimuth angle of the parabolic antenna can be roughly adjusted while confirming it with the magnetic needle of the azimuth magnet placed on the substantially horizontal surface of the mast mount.

【Example】

 Hereinafter, an embodiment of an antenna mounting device according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a structural view of a main part of an embodiment of an antenna mounting device according to the present invention. In the figure, (a) is a conceptual diagram showing the whole picture of the antenna mounting device, and (b) is an enlarged plan view of the compass magnet part provided on the upper part of the mast mount. In the figure, 1 in (a) is a cylindrical mast, which is erected substantially vertically. A mast mount 2 is rotatably attached to the upper part of the mast 1 and is fixed by a plurality of bolts 3. Reference numeral 4 is a compass for mounting the compass, which is mounted on the upper surface of the mast mount 2 substantially horizontally. Reference numeral 5 is an elevation adjustment metal fitting, which is fixed to the azimuth magnet mounting hardware 4 by tightening the elevation angle fixing bolt 6. A parabolic antenna 7 is fixed to the elevation adjustment metal fitting 5 with a bolt 8. 9 is an elevation angle adjusting rod, 10 is an elevation angle needle, and 11 is an elevation angle adjusting scale. Reference numeral 12 in (b) is an azimuth magnet, which is mounted on the azimuth magnet mounting bracket 4 so that the center of rotation of the magnetic needle coincides with the rotation axis of the mast mount 2.

The azimuth and elevation of the parabolic antenna are roughly adjusted as follows. First, the mast 1 is erected vertically on a desired base or the like, and the mast mount 2 on which the parabolic antenna 7 is mounted is fitted on the mast 1. Then, referring to the required azimuth / elevation tables attached to the parabolic antenna, turn the elevation adjustment rod 9 to adjust so that the elevation pointer 10 points to the required position on the elevation adjustment scale 11, and then the elevation fixing bolt. Tighten 6 and temporarily fix the elevation adjustment bracket 5. After that, loosen the bolt 3, turn the mast mount 2 while watching the direction of the magnetic needle of the azimuth magnet 12 on the azimuth magnet mounting bracket 4, adjust the azimuth angle to the required angle, and tighten the bolt 3. Temporarily fix the parabolic antenna. To adjust the azimuth, for example, check the azimuth of the area where the parabolic antenna is installed by referring to the table attached to the parabolic antenna, and put a mark etc. on the relevant part of the scale marked around the azimuth magnet 12. The mast mount 2 is rotated so that the tip of the magnetic needle is aligned with this mark.

As a result, the signal received from the broadcasting satellite is input to the satellite broadcasting receiver to which this parabolic antenna is connected, and the signal for adjusting the parabolic antenna is output. Finely adjust the elevation angle and azimuth angle of the above, and tighten the bolt 3 and the elevation angle fixing bolt 6 to fix the parabolic antenna. In order to prevent an error in the direction of the magnetic needle of the azimuth magnet 12, for example, the mast mount 2, the azimuth magnet mounting bracket 4, the elevation angle adjusting bracket 5 or the elevation angle fixing bolt 6 is made of a non-magnetizable metal or the like. Try to configure.
