propagation modes

Question

Sky wave propagation relies on reflection by:

RankGuru · Accepted Answer

Sky wave propagation involves radio waves (typically in the frequency range of 3 MHz to 30 MHz) that are directed towards the sky and reflected back to Earth by the **ionosphere**. The ionosphere consists of stratified layers of ionized gases at high altitudes. This mode of propagation enables 'over-the-horizon' or long-distance communication as the waves 'skip' between the ionosphere and the Earth's surface.
