ある。2. Description of the Related Art Antenna devices for receiving radio waves from geostationary satellites are roughly classified into outdoor type and indoor type. The outdoor type is, for example, an L-shaped antenna support 5 fixed to an outer wall 51 of a building as shown in FIG.
Since the planar antenna 55 is attached to the antenna 2 through the antenna mounting bracket 53, the elevation angle adjusting mechanism 54, etc., it has a large number of parts and is large in size, so it does not look good and has sufficient strength to withstand strong winds. Water resistance is required. Moreover, since it is often installed in a place where the scaffolding is poor or high, it may be difficult to adjust the elevation angle and the azimuth angle.

の都度調整しなければならない。On the other hand, the indoor type is disadvantageous in that the installation space is restricted by the direction of arrival of radio waves and the arrangement of windows, and the living space becomes narrow. Furthermore, there is a problem of deterioration of reception quality due to the attenuation effect of the window glass, and if the antenna cannot be fixed such as the floor-standing type, the set of elevation angle and azimuth angle easily collapses due to external force, so a stable image cannot be obtained, You have to adjust each time.

The angle θ 1 formed with 9 is set so that the plane antenna 14 has the minimum elevation angle when the axis 39 is horizontal. The antenna direction adjusting hole 13 has a lower end edge 40 at the screw shaft 3 of the adjusting knob 33 when the plane antenna 14 takes the minimum elevation angle.
4, the width of the antenna direction adjusting hole 13 in the vertical direction and the horizontal direction is set to the width required for adjusting the elevation angle and the azimuth angle of the planar antenna 14. The dielectric radome 10 has a hemispherical shape, and the inner peripheral surface portion 11 at the opening end thereof
Is fitted to the outer peripheral surface portion 37 of the mounting portion 12 of the antenna mounting tool 5 and fixed to the mounting portion 12 with the screw 20. This allows the plane
Antenna 14, antenna direction adjustment mechanism, etc. from wind pressure and rainwater
Be protected. Further, the dielectric radome 10 has a hemispherical shape.
Therefore, compared to the conventional flat radome type of outdoor antenna,
Less susceptible to dew. Figure 6 shows a hemispherical radome type
Shows an example of C / N characteristic curve of flat radome type night dew
You From this characteristic curve diagram, the hemispherical radome type is flat
Can you see that the C / N reduction rate is lower than that of the radome type?
It This is because hemispherical radomes are
It is located away from the tenor surface (antenna element plate),
The hemispherical radome has a narrower surface perpendicular to the direction of radio wave incidence.
It is thought that this is because the effect of night dew is small as it does not exist. Well
The hemispherical radome type is slightly behind the flat radome type.
The effect of night dew appears in the space inside the hemispherical radome.
It seems that it is large and it is difficult to be affected by the external temperature at first.
Be done.

Put the hand through the operation hole 4 to loosen the adjustment knob 33 a little, and slide the flat antenna 14 on the outer peripheral surface portion 25 of the bowl portion 7 by the adjustment knob 33 while checking the reception level with a satellite broadcast receiving tuner or the like. Then, the adjustment knob 33 is tightened and set at the position where the reception level is maximized. It should be noted that the positions of the planar antenna 4, the pressing tool 30 and the like shown by the two-dot chain line in FIG. 1 are the maximum elevation angle positions.
