Ali, samo je Tesla imao pravu viziju. On je emitirao signale sa definiranom frekvencijom i sa nizom antena osjetljivih na samo jednu frekvenciju detektirao je samo jedan signal i tako dobivao razumljiv prijenos.
But I think Tesla was the one with the real vision, in which he would broadcast signals on a definite carrier frequency and you would have a series of antennas sensitive to one frequency only tuned to a certain frequency,
