The introductory section of the presentation establishes how time-varying electrical currents transform into freely propagating electromagnetic waves. Alternating Current to EM Waves Antenna and Wave Propagation by K

High-frequency waves are radiated upward and refracted (bounced) back to Earth by the ionosphere—a layer of charged particles in the upper atmosphere.

Constrained by the optical horizon of the Earth. The maximum line-of-sight distance ( ) can be estimated using the antenna heights:
