The United States is moving broadcast TV to digital there are ATSC digital television only set top boxes none of these require any activation or card. The brand new receivers of this type are still currently expensive.
Their are old satellite TV receivers that can be used to watch ATSC digital television without paying for the service. I made some buyers guide web pages on this subject.
