##### SkyWave Skywave or skip refers to the [[propagation]] of [[Radio Wave|radio waves]] reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper [[atmosphere]]. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at intercontinental distances. It is mostly used in the shortwave frequency bands. >Covered in: [[C203 Week 1#Sky Wave|C203]] >Mentioned in: >References: [[WP Sky Wave|🌍]] >Required by: > >Related to: [[Space Wave]] [[Ground Wave]]
