WebRadio waves below 40 MHz are signi cantly a ected by the ionosphere, primarily because radio waves in this frequency range are e ectively re ected by the ionosphere. The E and F layers are the most important for this process. For frequencies beyond 40 MHz, the wave tend to penetrate through the atmosphere versus being re ected.
