摘要：PROBLEM TO BE SOLVED: To provide a communication antenna which is resistive to vibration caused, for example, by a strong wind. SOLUTION: The communication antenna is constituted of a cylindrical radiator and a cylindrical reflector which are coupled to each other at the upper and lower portions. A third supporting frame for the cylindrical radiator and reflector is provided in a predetermined location between a first supporting frame and a second supporting frame. The cylindrical radiator and the reflector are inserted into inserting holes which are formed with the alignment of the center axis lines in diameters larger than these of the cylindrical radiator and the reflector. A hollow cylindrical elastic material inserted into the inserting hole is provided on the internal circumferential surface of each inserting hole between the external circumferential surface of the cylindrical radiator and the reflector and the internal circumferential surface of the inserting hole in order to maintain in a normal condition the cylindrical radiator and the reflector to the center of each inserting hole, and to restrict the movement thereof within a predetermined range in a condition that the cylindrical reflector is curved like a bow.
