Poor Picture Quality 322 Receiver

[sbsi]

I got a 322 duel receiver, one tv hook up to receiver, one is sharing.

The picture quality without the receiver is getting worse and worse. There is a lot of fuzzy lines on the picture.

What is the best advice to fix it? Signal booster???

Either checking the fittings or re-running the TV2 coax line seems like the best bet
