Sandy Hook Telegraph Towers, Sandy Hook, NJ – 1913 This 1913 drawing depicts the Western Union and Postal Telegraph and Cable Marconi radiotelegraph towers located at Sandy Hook, New Jersey. The Postal Telegraph and Cable Co. was a competitor to Western Union. In 1943, Western Union merged with the Postal Telegraph and Cable Company. Burp! These wooden towers must have made terrific ranges for the local party boat fleet.
