That is, the hole 11 giving a dominant effect on the electric characteristic of the antenna is minimized. The side plate 10 is structured as an elliptic conical shell and a shell with the same Gaussian curvature zero as that of a cylindrical shell of a side plate of a conventional antenna, then the properties at the standpoint of the strength is nearly the same, but the size of the hole 11 is small enough to be different from that of the conventional antenna an only nearly 10% of the width of the side plate 10 is lost, and the continuity of the shell is sufficiently kept, the strength of the shell is maximized and no reinforcement is required. Since a box 12 is made small, the streamline of wind is less disturbed and the wind load is not almost increased. Thus, the antenna with less cause to the deterioration in the electric and mechanical characteristic is realized inexpensively.
