PURPOSE:To prevent the adhesion of snow, by providing small pieces having the shape of plate, rod or wire made of a type of material not interrupting electromagnetic waves such as plastic around a primary radiator or on a radome so as to move the small pieces with the wind force. CONSTITUTION:The small pieces 14 are plural wires made of a type of material not interrupting electromagnetic waves such as plastic and are mounted around the primary radiator 11 and on the radome 12. At snowfall, the snow adhered on the radome 12 and a support 13 is removed by the small pieces 14 driven by the wind force. Thus, the snow aound the primary radiator 11 and on the radome 12 is removed, allowing to prevent the gain reduction and the beam tilt. |
