Shortwave radio were required. It was also difficult to beam the radio wave directionally with long wave, resulting in a major loss of power over long distances. Prior to the 1920s, the shortwave frequencies above 1.5 MHz were regarded as useless for long distance communication and were designated in many countries for amateur use. Guglielmo Marconi, pioneer of radio, commissioned his assistant Charles Samuel Franklin to carry out a large scale study into the transmission characteristics of short wavelength waves and to determine their suitability for long distance transmissions. Franklin rigged up a large antenna at Poldhu Wireless Station, Cornwall, running on
Marconi Wireless Telegraph Company of America of United Wireless' tangible assets, which in turn on March 29, 1912 were sold by the parent company to American Marconi. It would later be alleged that this had unfairly benefited some British investors, in what came to be known as the Marconi scandal. The acquisition would prove to be a tremendous boost to American Marconi's fortunes, and the company boasted that "There is now nothing in the way of Marconi becoming the only system of commercial importance in the world." Recently passed laws required U.S. passenger ships to carry radio equipment, and American Marconi's near monopoly allowed it to
