Dipole antenna other monopole) antennas on the basis of dipole antennas of which they are one half. German physicist Heinrich Hertz first demonstrated the existence of radio waves in 1887 using what we now know as a dipole antenna (with capacitative end-loading). On the other hand, Guglielmo Marconi empirically found that he could just ground the transmitter (or one side of a transmission line, if used) dispensing with one half of the antenna, thus realizing the "vertical" or monopole antenna. For the low frequencies Marconi employed to achieve long-distance communications, this form was more practical; when radio moved to higher frequencies (especially
Premiata Forneria Marconi live performances included songs by groups such as King Crimson and Jethro Tull. Other early influences included Chicago, Ekseption, and The Flock. They had a long name, as Italian progressive bands tended to have back then (Banco del Mutuo Soccorso, Raccomandata con Ricevuta di Ritorno, etc.), and so were usually referred to as 'La Premiata', and later 'PFM'. After rejecting Isotta Fraschini (an Italian car maker) the group finally settled on Pagani's suggestion, 'Forneria Marconi' (meaning 'Marconi Bakery'), borrowed from the sign of a shop in the small town of Chiari, near Brescia. However, record producer and friend Alessandro Colombini
