星にこれを指向調整する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an antenna device installed in a communication ground station in a low latitude region so as to point toward a geostationary satellite, and particularly to a polar mount type antenna device. A polar mount type antenna device is rotatably supported around two axes. One axis is parallel to the earth's axis and is called the fixed axis. The other axes are perpendicular to this and are called movable axes. The main axis of the main reflector of the antenna device, that is, the axis that should be directed toward the satellite, is orthogonal to the movable axis. When installing the antenna device, the main reflector is rotated around both axes to direct it to the target satellite.

支持部とから構成される。 An antenna device is usually composed of an antenna section having an electrical function, such as an antenna main reflector, and a support section that supports the antenna section on the ground and has a mechanism for directing it toward a satellite.

から容易ではなかつた。 In the conventional polar mount system, the antenna part is supported by the support part at three points. Normally, the main reflector of this type of antenna part is approximately circular, so select three points equally spaced in the circumferential direction of this mounting member, for example, the mounting ring, and attach the fixed axis along a straight line passing through two of the points. was established. Therefore, the feed horn and the like protruding from the center of the antenna section to the support section sometimes interfere with the movement of the antenna section when adjusting the pointing towards the satellite. Therefore, in order to secure the space necessary for the movement of this antenna section, the number of support sections was set at four points. Furthermore, when changing the target satellite, it was not easy to adjust the rotation around the fixed axis because three points had to be supported at all times.

本発明のアンテナ装置の衛星指向時の調整につ
いて述べる。 The adjustment of the antenna device of the present invention when pointing to a satellite will be described.
まずストラツト１３，１４の長さを変えて直線
Ｈの回りに次にストラツト６の長さを変えて直線
Ｄの回りにアンテナ部を回転して衛星に指向させ
る。 First, the lengths of the struts 13 and 14 are changed around the straight line H. Next, the length of the strut 6 is changed and the antenna section is rotated around the straight line D to direct it to the satellite.

には３本の可変長のストラツト１３，１４，６を
用いるだけでアンテナを衛星に指向させることが
できる。他のストラツトは固定長のものでよい。 The lengths of the struts 15 and 16 are made variable, and the fixed axes are adjusted to be parallel to the earth's axis when installing the antenna device. Therefore, essentially only three variable length struts 13, 14, 6 are needed to direct the antenna to the satellite. Other struts may be of fixed length.
また指向すべき衛星が変更になつた場合等には
ストラツト１３，１４の長さを変えたり、必要に

ような構造であるため上記作業だけでなく、支持
部の分解についても組立順次と逆にこれを分解す
ることにより危険を伴なわずに小人数で作業を行
なうことができる。 For example, if you want to direct the antenna to a satellite in the eastern sky instead of a satellite in the western sky, first change the lengths of struts 13 and 14, make straight line D horizontal, and then attach one end of strut 14 to metal fitting 22. Replace the bracket 21 with the strut 13.
Replace it in the same way and adjust its length,
The strut 6 can achieve its purpose with only minor adjustments. Therefore, the antenna directional range can be doubled compared to the conventional antenna. Moreover, because of this structure, not only the above-mentioned work but also the disassembly of the support part can be carried out by a small number of people without any danger by disassembling it in the reverse order of assembly.
また金具８，９を通る直線上および金具１１，
１２を通る直線上にはいずれも軸は存在しないの
で、アンテナ部からの突出物のための空間を容易
に確保できる。 Also, on the straight line passing through the metal fittings 8 and 9, and on the straight line passing through the metal fittings 8 and 9,
Since no axis exists on the straight line passing through 12, it is possible to easily secure a space for a protruding object from the antenna section.
