    Annotation A dipole wire antenna of the Koch is considered. The antenna represents a wire dipole symmetrical with respect to the point of feeding. Arms of the dipole have the geometry of Koch prefractal. A family of antennas is singled out, in which the antennas differ from each other by an angle of arms turning. Antennas having the geometry of the first two iterations of a Koch curve are chosen for the analysis. Dipoles based on the Koch pre-fractals of the first two iterations having different wire thicknesses obtained by rotating one of the arms around a given coordinate axis is considered. Graphs depicting dependence of the base frequency and bandwidth for the frequency on angles of rotation around the axes are presented. Rotations of the dipole arms by small angles do not exert influence on the frequency and bandwidth. However, in the case of large angles of the arms rotation, the values of base frequency increase and bandwidth reduce significantly.
