PURPOSE:To direct the direction of a main beam easily in the direction of a geostationary satellite by providing a level meter measuring the horizontality and a direction adjusting section to the rear side of a reflecting mirror reflecting finally a radio wave irradiated from a primary radiator to attain ease of direction adjustment of the main beam and describing the district name such as city or prefecture name in place of the scale of a level meter. CONSTITUTION:The rear side of the reflecting mirror 2 is provided with an elevating angle adjusting section 4 and the level meter 8 and the angle of the reflecting mirror 2, that is, the direction of a radio wave to be directed in the geostationary satellite reflected on the reflecting mirror 2 is adjusted by referencing the level meter 8. In using a city name, prefecture name or a district name or the like in place of the scale of the level meter 8 and describing the name of each city to the position of the angle scale corresponding to each representing city, the direction of the main beam of the antenna device is directed easily in the direction of the geostationary satellite. |
