You can do observations during the day in most cases. Unlike with optical telescopes that use light from starts, which get covered by the sun. With radio telescopes they pick up radio waves which we can *seeany time of the day
We can build much bigger telescopes and telescope arrays. The biggest optical telescope is Keck 1 and 2 if I remember and those are 10m telescopes. The largest optical telescope array is also the pair of Keck telescopes which together act like a singe 20m telescope. The largest radio telescope is Arecibo telescope at 305m. And the largest radio array is ALMA, which has 50 antennas and can simulate a singe 16km antenna. So we can build a 600x larger antenna with radio than visual, and as we all know the bigger the better, and telescopes are no exception.
