Spare geostationary satellite at JSAT at SAT1 (150 ° E)
In the case of AT2 (154 ° east longitude), the distance is 4 ° from the center of the earth, but since the satellite broadcast receiving antenna is actually installed on the surface of the earth, the distance is about 5 ° from the surface of the earth. By setting the angle to 5 °, it is possible to easily adjust the azimuth of the satellite broadcast receiving antenna.

The undulating member 5 is made of sheet metal, and bends the swinging plate 27 from both sides of the mounting plate 26 so as to contact the outer surfaces of the side plates 14 of the rotating member 3. The parabolic reflector antenna 4 is screwed to the mounting plate 26 on the side opposite to the rocking plate 27 with screws or the like. Although the example of the parabolic reflector antenna 4 has been described, a planar antenna can be used instead of the parabolic reflector antenna 4.

And the horizontal support plate 7 using four bolts 40 to lower the horizontal rotation plate 2
3 and the lower horizontal plate 8 are fixed to the fixing member 2 by four bolts 42. When the bolts 40 and 42 are loosened, the rotating member 3 rotates about 30 ° in the horizontal direction about the through hole of the mast. At this time, at the portion where the fixed member 2 and the rotating member 3 are in contact with each other, 360 concave and convex strips 45 and 46 are provided.
Therefore, when it is rotated, a click sound is transmitted every 1 ° and vibration is transmitted to the hand of the rotating operator, and the angle of rotation can be confirmed every 1 °.

At this time, as shown in FIG.
It can also be attached to the mast 1 at an angle to the horizontal direction. This is because a geosynchronous satellite is usually located at about 36,000 km above the equator, but when trying to receive a different satellite than on the earth's surface, not only the azimuth angle but also the elevation angle changes.

When the upper through-hole of the U bolt 12 of the substrate 6 of the fixing member 2 is a perfect circular through-hole 50, and the lower through-hole is a through-hole 51 of an arc-shaped long hole centered on each through-hole 50,
Rotating vertically also changes the elevation angle. When the antenna is installed, the fixed member 2, the rotating member 3, and the up-and-down member 5 are attached to the mast 1 to receive a target radio wave from a geostationary satellite.
The parabolic reflector antenna 4 is aligned with the direction of the target geostationary satellite. The azimuth angle is U bolt 12 attached to the fixed member 2.
Is loosened, the elevation angle loosens the fixing bolt 31 attached to the undulating member 5, and the parabolic reflector antenna 4 is undulated. After adjusting the direction so as to obtain the maximum reception level, the bolts 40 and 42 and the fixing bolt 31 are fixed.

Thereafter, when the radio wave from the geostationary satellite being received is interrupted due to a failure or the like, or when it is necessary to temporarily switch to another geostationary satellite for reception, the position of a spare geostationary satellite or the like is changed. When receiving another known geostationary satellite, the bolts 40 and 42 and the nuts 41 and 43 that fix the fixed member 2 and the rotating member 3 are loosened and rotated in the horizontal direction.

In this case, fine adjustment within 1 ° may be necessary. However, since the half value angle of the antenna for receiving a geostationary satellite for broadcasting is 1 ° or more, there is no problem in practical use. Then, the U bolt 12 of the fixing member 2 may be loosened for fine adjustment. FIG. 4 shows an example in which a satellite switching mechanism is provided at a location different from the azimuth adjustment mechanism described above. The mast 61 is divided, fixing a horizontal support plate 67 to the upper end of the lower mast 61 _1, which was fixed horizontally rotating plate 82 to the lower end of the upper mast 61 _2, others are the same as described above in Example. Note that reference numeral 6
4 is a parabolic reflector antenna.

In FIG. 1 and FIG. 4, four arc-shaped long holes of the horizontal rotating plate are provided. However, it is also possible to divide the horizontal turning plate into three equal portions to make three holes. In this case, the horizontal supporting plate has three bolt holes. Need to be part. The three-point arrangement can have a larger central angle than the four-point arrangement.
