That photo is an interferometer array operating at very short wavelengths (mm) . It was built by NRAO (National Radio Astronomy Observatory). I worked for them for 14 years. Here is one that was in Green Bank, WV, a140 ft single dish. We detected the first H109a spectral line with it. That's (L-R) Dr Peter Mezger, telescope operator, Dr Bertil Hoagland, and me. This was about 1965.
