Alfonso Marconi 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 in 1865, the first son of Giuseppe Marconi (an Italian aristocratic landowner from Porretta Terme) and of his Irish/Scots wife, Annie Jameson (daughter of Andrew Jameson of Daphne Castle in County Wexford, Ireland, and granddaughter of John Jameson, founder of whiskey distillers "Jameson & Sons"). Alfonso was educated at Bedford School in England between 1876 and 1880, during his peripatetic childhood.
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
