How does hertz produce radio pulses

WebWhen the induction coil connected to the first loop (the transmitter) produced a high voltage discharge, a spark jumped across the gap, sending out a signal that Hertz detected as a weaker spark across the gap in the receiving apparatus, which he placed nearby. Pulsed radiofrequency is the technique whereby radio frequency (RF) oscillations are gated at a rate of pulses (cycles) per second (one cycle per second is known as a hertz (Hz)). Radio frequency energies occupy 1.0 x 10 Hz to 3.0 x 10 Hz of the electromagnetic spectrum.
