(large 305m radio telescope in Puerto Rico)

Arecibo Observatory (NAIC, National Astronomy and Ionosphere Center) is a 305m Radio Telescope in Puerto Rico built using a depression in the ground. It is the largest single-Aperture telescope. It uses its full 305m when aimed vertically, and can be aimed to roughly 20deg from the zenith, though its effective aperture is reduced.

ALFA (The Arecibo L-Band Feed Array) detects Radio at 1225 to 1525 MHz (nominally 1.4GHz or 21cm Line), useful for HI observations.
