Tv today

You didn't really say if the TV is an older analog one or a newer digital
one. Unless I missed it.
As was said analog you will need a digital converter box.
They work just fine. We had one on our old tv before the tv died.

Was the TV working fine before the move? Maybe something got messed up
in the TV when you moved.

It may be just a case of adjusting the outside antenna direction.

Hope you figure it out.
