Check the cable. You may have had a hungry rat or squirrel chewing on your wires. If that doesn't reveal any problem, plug the antenna input into a different TV and see if that works. If so, it's your TV. If not, it's the antenna or cable. If the first two fixes don't work, try running a second cable from the antenna to the TV to completely bypass the original cable. Finally, verify that the antenna is positioned properly and didn't get blown off line or something.
