List of radio telescopes

From Wikipedia, the free encyclopedia

This is a list of radio telescopes that are or have been used for radio astronomy. It includes both single dishes and interferometer arrays. They are listed by region, then by name; unnamed telescopes are in reverse size order at the end of the lists.

This list is incomplete; you can help by expanding it.
