Here is a quick guide for the exhibits at ISEC.
Exhibit 1. The SCR271 antenna that was used during Project Diana to demonstrate that the ionosphere could be penetrated at VHF (very high frequencies) from the Earth and from above the Earth. It’s predecessor, The SCR270 was retrofitted with a larger spring board and better transmitter. It was with this antenna that the Moon Bounce was achieved on January 10, 1946. With that success we could radio to communicate with spacecraft.
This site became known as the Diana Site after the history changing Moon Bounce. The team of Project Diana included Col. John DeWitt, E. King Stodola and Harold Webb as well as others. Walter McAfee correctly calculated the distance from the Moon to the Earth. The success of the Moon Bounce led to the development of space exploration.
The Diana Site in the late 1940’s and early 1950’s continued to be a radar research facility . In this aerial photograph one can see radar trucks, the tower that stands behind the building today, The SCR271 as well as smaller antennas used for radar research. Notice the minimal housing development that there is along the Belmar shore of the Shark River. The SCR271 was later disassembled.
