WebAs frequency is scanned on an ionosonde, return signal is obtained resulting from reflection of the transmitted signal from the ionosphere. However, at the critical frequency, the return decreases greatly, as the transmitted signal passes through the ionospheric layer rather than being reflected. There are critical frequencies measurable for the E, F 1, and F 2 … Web22 okt. 2003 · The lower the frequency of transmission the more the electron moves and the more likely it is to be absorbed.
