This is an obscure type of antenna, called sometimes cigar antenna, that works pretty much like Yagi - most of you will know it as (non-satellite) TV antenna - but instead of rods it has disks. It was used in Lunokhod 1 and 2, Soviet moon rovers launched in 1970 and 1973 respectively
Where was that picture taken? Looks like a cool museum I’d like to add to my bucket list.
Edit: Did a quick reverse image search, and it’s apparently the NPO Lavochkin museum in Moscow. Also seems to be an old photo. The museum has been renovated since and looks much, much nicer now. https://www.leonarddavid.com/take-a-virtual-tour-russian-museum-of-cosmonautics/
i’ve lifted this photo from linked page, which elaborates on these antennas in detail
