The Marconi Wireless Station Site in South Wellfleet, Massachusetts is the site of the first transatlantic wireless communication between the United States and Europe. At this location, now in the Cape Cod National Seashore, inventor Guglielmo Marconi erected a large antenna array on four wooden towers, and established a transmitting station powered by kerosene engines that produced the 25,000 volts of electricity needed to send signals to a similar station in Poldhu, Cornwall, United Kingdom. The first transmissions received in North America by Marconi were at Signal Hill, St. John's, Newfoundland and Labrador in 1901 and Glace Bay, Nova Scotia in 1902.〔(【引用サイトリンク】title=Marconi and his South Wellfleet Wireless )〕 One of the station's most notable roles occurred with the sinking of the RMS ''Titanic'' in April 1912. Operators at the station were able to alert the RMS ''Carpathia'' so that the rescue of some of the ''Titanic'' passengers could be effected. The station was shut down in 1917 in part over concerns about its use in World War I, but also because its towers were threatened with erosion. In 1920, usable materials and equipment were removed from the site, and it was abandoned. Erosion has taken its toll over the years since then, and there was little left as of the date of the National Park Service brochure.〔 No trace of the site remains as of September 2014; the sea has claimed it all. Marconi had moved the station to Chatham by 1912 and the Titanic and Carpathia communications were done from there. There is debate of whether the Wellfleet station was ever put into commercial operation. The site was listed on the National Register of Historic Places in 1975.〔 ==Gallery== File:Remains of the Marconi Station in Wellfleet.jpg | Remains of the Wellfleet station's towers, 2009 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Marconi Wireless Station Site (South Wellfleet, Massachusetts)」の詳細全文を読む スポンサード リンク
