Abstract

PURPOSE:To completely melt snow on an antenna mirror surface and to decrease the distortion of the antenna mirror surface, by effectively dissipating generated heat. CONSTITUTION:A heat insulation member 5 is fixed to enclose a frame construction 2 holding an antenna mirror surface 1 and a hot air generator 4 is arranged. The hot air from the hot air generator 4 is circulated in a closed space between the antenna mirror surface 1 and the heat insulation member 5 fixed to surround the frame construction 2 so that the frame construction 2 and the antenna mirror surface 1 can be heated equally to completely melt the snow on the antenna mirror surface. Since the temperature of the antenna mirror surface is uniform, the distortion of the antenna mirror surface caused due to unequality of temperature can be decreased.
