History of radio the journal RPCS). An earlier description of the device was given by Dmitry Aleksandrovich Lachinov in July 1895 in the second edition of his course "Fundamentals of Meteorology and Climatology", which was the first such course in Russia. Popov's receiver was created on the improved basis of Lodge's receiver, and originally intended for reproduction of its experiments. In 1894 the young Italian inventor Guglielmo Marconi began working on the idea of building a commercial wireless telegraphy system based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did not seem to be
Guglielmo Marconi maximum transmission distance for radio waves. A breakthrough came in the summer of 1895, when Marconi found that much greater range could be achieved after he raised the height of his antenna and, borrowing from a technique used in wired telegraphy, grounding his transmitter and receiver. With these improvements, the system was capable of transmitting signals up to and over hills. The monopole antenna reduced the frequency of the waves compared to the dipole antennas used by Hertz, and radiated vertically polarized radio waves which could travel longer distances. By this point, he concluded that a device could become capable
