I don't have cable or satellite, we hooked outdoor antenna up and have had great reception but not now, WHY!!? | Yahoo Answers
ever since television stations went digital we have had our televisions hooked up to an outdoor antenna and have gotten great reception until about two weeks ago now we have no signal, why has this happened and can we do anything to correct it???
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.
