Well, where do you live? If you are within 20 miles of a Fox station transmitter, you should be able to pull in a perfect HD picture with even an indoor TV antenna. Otherwise, if you are up to 50 miles away, you’d need a bigger antenna.
I assume you are just getting your cable signal from the wall outlet, in which case you may only be able to get standard definition. But most cable companies allow you to get the broadcast channels in HD, without a digital box. If they have scrambled all the HD channels, you will have to go pick up an antenna and pick up Fox over the air.
