Camp Evans Historic District
Camp Evans Historic District is an area of the Camp Evans Formerly Used Defense Site in Wall Township, New Jersey. The site of the military installation () is noted for a 1914 transatlantic radio receiver and various World War II/Cold War laboratories of the United States Army (e.g., signal, vacuum tube, dosimetry, & photo-optics). From 1925 to 1935 the site was the headquarters for the New Jersey Ku Klux Klan.〔
==Belmar Receiving Station==
The Belmar Receiving Station was established near the Belmar community together with a separate transatlantic transmitting facility at New Brunswick, New Jersey, by the American Marconi Company. The Belmar station included "a mile-long bronze-wire receiving antenna strung on six 400 foot tall masts with three 150 foot balancing towers along the Shark River. Outgoing Morse-code messages were sent via a telegraph land-line from the Belmar Station to the transmitter." The receiving site also had a telegraph land-line to a New York office.〔NRHP Registration Form, citation 16: 〕
Original buildings〔http://books.google.com/books?id=r8BPAAAAMAAJ&pg=PA360&dq=clifden+marconi&lr=&as_brr=1#PPA360,M1〕 () were built by the J.G. White Engineering Corp. between 1912 and 1914 as part of Guglielmo Marconi's "wireless girdle"〔(Bucher - Practical Wireless Telegraphy - 1920 ed )〕 around the Earth. In one of the buildings being constructed for the Belmar station, the regenerative circuit was demonstrated on January 31/February 1, 1914.
In April 1917, the Belmar station was acquired as part of the Navy's World War I "Trans-Atlantic Communication System" and after the November 1918 Armistice with Germany, Marconi Wireless Telegraph Company of America regained the Belmar station,〔(Guglielmo Marconi )〕 which Radio Corporation of America owned from October 1919 until 1924.
