Marconi employed electric waves of high frequency set up by an induction coil in an oscillator, these waves being launched into space through a lofty antenna. The receiving apparatus consisted of another antenna in circuit with a coherer and  small battery for operating through a relay the ordinary telegraphic receiver. This apparatus contains the essential features of all the systems now in use.
