For sky wave propagation of a 10 mhz signal

WebThe ionospheric layers used for skywave propagation are layers D, E, and F (which splits into F1 and F2 when sufficiently ionized). The height of the layers follows alphabetical order. The lowest layer D (at a height of 30 to 60 miles) is the ionospheric layer that is closest to the surface of the earth. For more info see Wikipedia: D region
