Conventionally, as this type of method for positioning and adjusting the sub-reflector, there have been methods shown in FIGS. 3 and 4. Third
In the figure, a positioning jig 11 is set on the mirror axis of the main reflecting mirror 1, and a reference hole 6 is placed on the jig 11.
This is a method of placing the sub-reflector 10 having a shape and determining its position. In addition, FIG. 4 shows that the tip of the sub-reflector 10 is passed through a positioning jig 11 set on the mirror axis of the main reflector, its height and eccentricity are determined by the jig 11, and its inclination is determined by a dial gauge 12. This is a method of adjusting the sub-reflector 10 by rotating the sub-reflector on the circumference of the reflecting surface so that the readings of the dial gauge 12 become the same.

The third method of positioning and adjusting this conventional sub-reflector
In the figure, the sub-reflector 10 is
It is necessary to increase the size of the pedestal of the jig 11 on which the jig is placed, and as a result, the weight of the jig increases, making it extremely difficult to handle.

いため、調整時間が増大する等の問題があつた。 In addition, the method shown in FIG. 4 can achieve high accuracy by simply adjusting the inclination, but it requires repeating the dial gauge 12 many times while rotating the reflective surface of the sub-reflector 10 on the circumference. Since it is difficult to achieve accuracy, there are problems such as increased adjustment time.

とする。 In the present invention, the antenna sub-reflector has a reference hole that coincides with the antenna mirror axis, passing through it from the reflecting surface side to the back cover side, and the positioning jig for the antenna mirror axis has a diameter that allows it to fit through the reference hole. The method is characterized in that positioning is performed using a device having a length and a length.

First, the sub-reflector 2, which has a reference hole 6 on the reflecting surface side and a through-hole 7 on the back side, is inserted into the positioning jig 3 fixed to the mirror axis of the main reflector 1 to the back side and set. do. Next, the spherical end fitting 4 of the sub-reflector 2 is fixed to the sub-reflector mounting column 5, and then the positioning jig 3 is removed, thereby fixing the sub-reflector 2 in a predetermined position with the desired precision. be done.

As explained above, in the present invention, the positioning jig fixed on the mirror axis of the main reflector is fixed to the sub-reflector by penetrating the sub-reflector provided with the reference hole.
Eccentricity, inclination, and height can be simultaneously positioned at the desired position with the desired accuracy, eliminating the need for any conventional adjustment process, which has the effect of significantly shortening the time for positioning and adjusting the sub-reflector. . Further, according to the present invention, it is possible to position and attach the sub-reflector even when the main reflector is tilted.
There is also the advantage that the positioning of the sub-reflector can be done taking into account the deflection of the sub-reflector mounting bracket in the communication direction.
