Alfonso Marconi become capable of spanning greater distances and would prove valuable both commercially and militarily. Alfonso Marconi was a director of the American International Marine Communication Company and an avid collector of stringed instruments. He died suddenly at a London hotel on the evening of Friday 24 April 1936 following a heart attack (his brother died following a heart attack in 1937). Alfonso Marconi Alfonso Marconi (18651936) was an Italian businessman and collector of stringed instruments, most famous for assisting his younger brother Guglielmo Marconi in his pioneering work on long-distance radio transmission Alfonso Marconi was born into the Italian nobility
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
