Antenna not working anymore

[rogercasteel22]

Help!
We've been using a over the air antenna for the past year now and for the first 7 or 8 months the signal was perfect all the stations came in fine.but now in the last past 4-5 months the signal has been horrible and some stations we use to get only come in during evening time now.other stations also break up alot when your watching them and this is so strange considering this never happened when we first started using the antenna.im wondering if the antenna has possibly gone bad or if it's the cable running from the TV to the antenna that's gone bad.any help is appreciated

Cable and everything in between, splitters.

Is this a rooftop/attic antenna? have somebody "disturbed" its orientation?

Also, do you use an amplified connection? If so, make sure it is still getting power.
