WebSky Wave Propagation is a term used for the radio signals which pass through the space or sky. It is also known as radio wave propagation because it is neither refracted nor reflected back to the Earth from the ionosphere. Among all kinds of electromagnetic waves, radio waves are extensively used in day-to-day life. WebFor the frequencies above 30 MHz, the sky wave propagation exists. Signal multipath is the common problem for the propagation of electromagnetic waves going through Sky wave. The wave, which is reflected from the ionosphere, can be called as a hop or skip.
