摘要
Topic To make dissipation power unnecessary, furthermore, it is simple and can be possible, make cheap configuration the antenna device which is offered.SolutionsAs for the dish antenna, refractor 1 of the parabolic condition which reflects radio wave is provided, aperture side of this refractor 1 is covered by cover 5. Cover 5, as angle of contact has the water repellency Characteristic of 110 degrees or more, the flexibleness which possesses radio wave transmission make consists of the high density web of area thin, has with the front cover 5a which covers the aperture side of refractor 1 and the adapter unit 5b which unites the rim edge with the elastic string on back side of the dish antenna. Deformation unrestricted elastic body 7 distribution facilities is done, to with the cover 5 which is located on upper part side of refractor 1, the angle of elevation which is formed by the front cover 5of a cover 5 is made smaller than angle of elevation of refractor 1.
