FIG. 2 shows a conventional offset parabolic antenna, in which A is a side view, the mouth is a front view, and C is a front view showing the outline shape of the reflecting surface. Fig. 3 is a perspective view showing the reflecting surface of a standard parabolic antenna to which the structure of the present invention is applied, Fig. 4 is a partially enlarged view showing the structure of the heating means on the same reflecting surface, and Fig. 5 is a perspective view of the reflecting surface of the standard parabolic antenna to which the structure of the present invention is applied. Another application example is shown in which the present invention is applied to a parabolic reflecting surface (standard type) with a multi-curved surface configuration. FIG. 6 shows an offset type parabolic reflecting surface having a compound curved surface configuration, where A is a longitudinal side view and the mouth is a front view (projection view in the thickness direction).
