Antenna DESIGN SECTION
J. Ruze was Head of the Antenna Design Section and A. Kampinsky was a senior member of his team. They were approached by Jack DeWitt early on to design an antenna that would serve the unique needs of Project Diana. Ruze and Kampinsky responded by proposing a system described by Herbert Kauffman as "using quarter-wave step-up transformers on the 250-ohm line with open spark gaps on the ends of the quarter-wave TR and ATR. But [Kauffman continued] the gaps would not last because of the unusually long pulses, although normally they work very well on conventional radar sets where the pulses were very short and the average power is low." When the system failed to work even after extensive efforts to tweak the transmitter, DeWitt fell back on the resources of his own team, who came up with the iconic "bedspring" design that was ultimately used in the successful moon bounce.
