WebMay 6, 2024 · This is rather well known, radio propagates effectively by ground waves for long and medium wave and the top of shortwave, with the distance progressively shorter and shorter - from thousands of kilometres for the LW. Note that even UHF is not quite line of sight only, but can diffract slightly around the horizon, hills and buildings. WebThe ionosphere exists between about 90 and 1000 km above the earth’s surface. Radiation from the sun ionizes atoms and molecules here, liberating electrons from molecules and creating a space of free electron and ions. Subjected to an external electric eld from a radio signal, these free and ions will experience a force and be pushed into motion. fridges on amazon
