Each slide identifies the frequency and orientation (vertical plane or horizontal plane). The maximum gain (red line) and -3 dB gain points (green lines) are marked. A short horizontal red line near the center of most plots represents the antenna structure, oriented broadside to the viewer. For 40 - 10 m, 3D color plots are also included. A white line in those plots represents the antenna structure. x, y and z axes (barely showing) are in green.
