。(Prior Art) Generally, this type of I! The Li star broadcast receiving antenna uses a reflector with a diameter of about 1 m, and because its reception frequency is high at 12 GHz, it requires highly accurate directivity with a half-width of about 2 degrees. . Therefore,
When installing a wT star broadcast receiving antenna, connect the AGC level meter 1 to the television receiver 2 as shown in Figure 4.
The AGC (automatic gain control) terminal 3a provided in the tuner 3 is connected via a cable 4 to the reflection mirror 5. While observing the AGC level meter 1, the direction of directivity (azimuth/elevation) is determined by the maximum value. ) was set.
ところが、上記衛星放送受信アンテナでは、その構成上
、強風等の気象条件により反射鏡に大きな風圧をうける
ために、その指向方向にずれが生じ易く、その都度、上
述したようにＡＧＣレベルメータ１を用いて指向調整を
行なわなければならず、その取扱いが非常に面倒なもの
であった。However, due to the structure of the above satellite broadcast receiving antenna, the reflecting mirror is subjected to large wind pressure due to weather conditions such as strong winds, so it is easy to misalign the pointing direction. The directivity adjustment had to be carried out using the same method, and the handling was extremely troublesome.
また、一般家庭等の場合には、上記ＡＧＣレベルメータ
１を用いずに直接的に、テレビジョン受像！ｆ１２の画
像を観察しながら、指向方向の調整を行なう方法も採ら
れていた。In addition, in the case of a general household, etc., television reception can be performed directly without using the AGC level meter 1. A method of adjusting the pointing direction while observing the f12 image has also been adopted.
しかしながら、この方法の場合には、反射鏡５の近傍に
テレビジョン受像機２を設置しなければならなかったり
、あるいはその都度、反射鏡５近傍までテレビジョン受
像機２を持っていかなければないという問題を有する。However, in the case of this method, the television receiver 2 must be installed near the reflecting mirror 5, or the television receiver 2 must be brought close to the reflecting mirror 5 each time. There is a problem.
