摘要：PURPOSE:To prevent snow and ice from adhering to an antenna without deteriorating a characteristic of the antenna, by providing a conductive heating element on the inside of the antenna. CONSTITUTION:A conductive heating element 15 having a return feeder is provided extending from the tip of the inside of a radiant element 3 to the inside of a gap 5 between a cylinder 1 and 2, and connected to a core wire 17 of a shield wire 16 through a hole 8. A conductive heating element 18 is also the same. These heating elements are insulated from the radiant elements 3, 10, a balanced-to-unbalanced converter, and an external conductor 4 of a high frequency coaxial line. The heating elements 15, 18 are provided on the inside of the radiant elements 3, 10 and the inside of the balanced-to-unbalanced converter, therefore exert no influence on a high frequency current flowing through the outside surface of the radiant elements 3, 10 and the outside surface of the balanced-to-unbalanced converter. Accordingly, a current from a heating power source 19 heats the heating elements 15, 18 without deteriorating a characteristic of an antenna.
