Parabolic antenna be exploited. Italian radio pioneer Guglielmo Marconi used a parabolic reflector during the 1930s in investigations of UHF transmission from his boat in the Mediterranean. In 1931 a 1.7 GHz microwave relay telephone link across the English Channel using 10 ft. (3 meter) diameter dishes was demonstrated. The first large parabolic antenna, a 9 m dish, was built in 1937 by pioneering radio astronomer Grote Reber in his backyard, and the sky survey he did with it was one of the events that founded the field of radio astronomy. The development of radar during World War II provided a great
Radio Marconi the development of proprietary technologies in 2006 and started its international expansion, with the first international project realized in 2007 at the Oslo Opera House. The company made a patent application in Italy in November 2007. In 2009, it further developed technology aimed at low consumption multimedia technology (known as MODE23). Patent applications were expanded to Europe, United States, Canada, China, Oman, Qatar and United Arab Emirates. In 2010, the company obtained a patent for its MODE23 technology in its native country. Its applications extend to other parallel markets, such as those involved with sport. In 2011, Radio Marconi was
