Abstract
PURPOSE:To facilitate the fitting of a horn to a dielectric film cover by reducing the thickness of the horn by forming many perforations at the circumference of the cover, by running yarn through the perforations, and tying the yarn on the vertex side of the horn. CONSTITUTION:A horn 1 having uniform thickness is provided with a triangularly sectioned ring 7 so that the vertex of the triangle and an opening surface are coincident with each other and one side of the triangle comes into close contact with the external wall of the horn 1. Many perforations 5 are formed more closely to the vertex side of the horn 1 than to the ring 7 of a dielectric film cover 3 which covers the opening part of the horn 1, and yarn 4 is run through them. The dielectric film cover 3 is fitted to the horn 1. Thus, the thickness of the external wall of the horn 1 is reduced and the cover 3 is detached easily.
