The scientist who first sent electromagnetic waves to distant places was Heinrich Hertz (German physicist, 1857-1894). He applied Maxwell's theories to the production and reception of radio waves.

When waves created by the sparks of the coil transmitter were picked up by the receiving antenna, sparks would jump its gap as well. Hertz showed in his experiments that these signals possessed all the properties of electromagnetic waves.
