In the former antenna radome, for example, the temperature fluctuation range of the components of the antenna installed in the radome changes greatly in response to changes from the condition of direct sunlight to the condition of being shaded by sunlight in outer space. Sometimes. Also, in the latter antenna radome, where the temperature control coating is applied to the entire outer surface of the semiconductor thin film layer, electric charges may accumulate on the coating surface and electrostatic discharge may occur if the charging potential exceeds the limit. There is. When this discharge occurs, noise electric waves generated by the discharge of all the electric charges accumulated on the coated surface at one time give electromagnetic interference to other devices.
