 It was the inspiration for later EME (Earth-Moon-Earth) communication techniques.At a laboratory at Camp Evans (part of Fort Monmouth), in Wall Township, New Jersey, a large transmitter, receiver and antenna array were constructed for this purpose.The transmitter, a highly modified SCR-271 radar set from World War II, provided 3 kilowatts (later upgraded to 50 kilowatts) at 111.5 MHz in -second pulses, applied to the antenna, a "bedspring" reflective array antenna composed of an 8x8 array of half wave dipoles and reflectors that provided 24 dB of gain.
