This is a flight-qualified but unflown antenna system used by the crew of the Apollo Lunar module to communicate with the astronaut on board the Command Module, and to NASA ground sations. The system operated in the "S-Band" of frequencies: between 2,000 and 4,000 MHZ. The Lunar Module did not return to Earth, and therefore no flown specimens of these antennas were returned.

NASA transferred this antenna to the Museum in 1977.
