Though, as the linked article explains, you can’t use the entire 500m as a single aperture. You can only use 300m of it at a time, but you can “point” it in different directions by using different 300m windows.
There’s also https://en.wikipedia.org/wiki/RATAN-600, with a diameter of 575m, but that isn’t a fully filled dish.
