【従来の技術】 衛星から送信される電波方式が直線偏波である場合、受信側 の平面アンテナ２１の偏波面の角度を一致させることが必要である。従来の平面 アンテナ取付け構造は、図３に示すように、平面アンテナ２１の背面に、左右対 象の形状をし、２個からなるアダプタ２２の一方のフランジの穴を介してネジＡ ２３により固定され、また、アダプタ２２の他方の側面は、ポール２４に取り付 つけられているマストマウント２５の側面のネジ穴にネジＢ２６により固定され ている。このような方法では、衛星に対して平面アンテナ２１を水平と垂直方向 に角度を変え合わせる機能のみを有するもので、受信する衛星の違い、平面アン テナ２１の設置する地方の違い、または、ポール２４が垂直に設置されていない 場合等の原因によって、ポール２４に対して平面アンテナ２１の偏波面の角度は 必ずしも一定しない。従って、受信する衛星の偏波角度に合わせるために、平面 アンテナ２１を回転方向に角度を変える必要がある。この微調整をする方法とし て、平面アンテナ２１の背面側とアダプタ２２のフランジの穴を介して固定する ネジＡ２３を緩め、この穴径とネジＡ２３との間の余裕寸法により若干の角度を 微調整するか、若しくはポール２４の設置角度を修正する等しているため、衛星 から送信される電波を受信するまでには複雑多岐にわたる調整作業を必要として いた。2. Description of the Related Art When the radio wave transmitted from a satellite is a linearly polarized wave, it is necessary to match the angles of the planes of polarization of the plane antennas 21 on the receiving side. As shown in FIG. 3, the conventional planar antenna mounting structure has a left-right shape on the back surface of the planar antenna 21, and is fixed by a screw A 23 through a hole in one flange of the adapter 22 consisting of two pieces. The other side surface of the adapter 22 is fixed to a screw hole on the side surface of the mast mount 25 attached to the pole 24 with a screw B26. In such a method, the plane antenna 21 has only a function of changing the angle of the plane antenna 21 in the horizontal and vertical directions with respect to the satellite, and the difference in the receiving satellite, the difference in the region where the plane antenna 21 is installed, or the pole. The angle of the plane of polarization of the planar antenna 21 with respect to the pole 24 is not always constant due to causes such as the case where 24 is not installed vertically. Therefore, it is necessary to change the angle of the planar antenna 21 in the rotating direction in order to match the polarization angle of the satellite to be received. As a method of making this fine adjustment, loosen the screw A23 that is fixed through the hole on the rear surface of the planar antenna 21 and the flange of the adapter 22, and slightly adjust the angle depending on the allowance between the hole diameter and the screw A23. Since it is adjusted or the installation angle of the pole 24 is corrected, complex adjustment work was required before the radio waves transmitted from the satellites were received.

FIG. 1 is a side view showing an embodiment of the planar antenna mounting apparatus of the present invention, and FIG. 2 is a perspective view of a main part of the planar antenna mounting apparatus of the present invention. In the figure, 1 is a pole, which is fixed to four bolts 4 by inserting the pole 1 between the mast mount 2 and the mounting metal fitting 3 on the top of the pole 1, and the lower part of which is not shown, such as the ground. It is installed in. Reference numeral 5 denotes an adaptor, and the adapter 5 is formed in a U shape having an inclined surface on one side, and the antenna fitting portion 6 having a cylindrical shape is integrated with the inclined surface on one side by, for example, welding. At least one predetermined position of the metal fitting mounting portion 6 is provided with a threaded hole so that at least one rotation stop screw 7 can be inserted. Reference numeral 8 is a plane antenna, and the angle of the plane of polarization of the plane antenna 8 is adjusted to the angle of the linearly polarized wave received from the satellite, and the signal is connected to a receiver (not shown) by a coaxial cable 10 via a converter 9.

【０００７】 次に衛星から受信する直線偏波に合わせる方法を説明する。前記アダプター５ と一体となっているアンテナ金具取付部６に、前記平面アンテナ８の背面に取り 付けられたアンテナ金具１１を挿入し、衛星から受信する直線偏波の角度に平面 アンテナ８を微細に回転しながら偏波面の角度を合わせ、前記回転止めネジ７を 締結して固定する。従って、平面アンテナ８の偏波面は、任意の角度に設定でき るため、ポール１が垂直に設置されていない場合、受信する衛星の違い、または 、設置する地方が異なることによる偏波面の角度の違い等に対して、平面アンテ ナ８の偏波面の角度を容易に合わせることができる。Next, a method of adjusting to the linearly polarized wave received from the satellite will be described. The antenna fitting 11 attached to the back surface of the planar antenna 8 is inserted into the antenna fitting mounting portion 6 integrated with the adapter 5, and the planar antenna 8 is finely adjusted to the angle of the linearly polarized wave received from the satellite. While rotating, the angle of the plane of polarization is adjusted and the rotation stop screw 7 is fastened and fixed. Therefore, the plane of polarization of the plane antenna 8 can be set to an arbitrary angle, so if the pole 1 is not installed vertically, the angle of polarization of the plane of polarization will differ due to the difference in the satellites to be received, or due to the difference in the installed region. The angle of the plane of polarization of the planar antenna 8 can be easily adjusted to the difference.
