A portable S-band antenna was erected by the astronauts of Apollo 12 and Apollo 14 during their initial EVA. Stowed in a special compartment on the Lunar Module's descent stage, the large 3 meter unfurlable dish on a tripod allowed for the transmission of large amounts of data as well as color TV images to the various Apollo tracking stations on Earth,
This antenna was stowed on Lunar Module #2 at the time of its transfer to the Museum for display, possibly to accurately replicate weight distribution during earlier LM-2 drop tests. It was discovered during refurbishment of the Kapton coatings on the LM-2 display in 2012. The LM-2 was transferred to the Smithsonian in 1970.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
