Ionosphere and radio
WebThe Ionosphere: The earth’s ionosphere is responsible for the over-the-horizon radio signal propagation that we enjoy with HF and occasionally with VHF. The ionosphere is comprised of layers of the atmosphere in which electrically charged particles are created that collectively have a bending effect on RF signals, directing them back toward the … Web11 mrt. 2024 · We can have two-way radio communication between Iceland and Australia and places in between because voice, video and data signals may be bent back to earth by the ionosphere. The ionosphere is shell of electrons and electrically charged atoms and molecules (ions) that surrounds the Earth, stretching from a height of about 50 km (31 …
