Dish PPV is not broadcast content (programming originating from a broadcast network: ABC, CBS, NBC, Fox or PBS).
Dish PPV is offering movies and other non-broadcast content in 1080p...see
this Dish TV press release regarding 1080p programming.
If you read the full
TurboHD channel line-up, you will see there is no network television content listed (ABC, NBC, CBS, Fox, PBS). Dish offers the opportunity to add local HD network channels, but these will be in 1080i, because no network is yet broadcasting in 1080p (and there is no programming being delivered to the networks in 1080p because the network HD delivery requirements specify 1080i at present), as I explained earlier.
But, all this discussion of Dish PPV and 1080p is moot, because the OP owns a non-1080p CRT television, and he is asking about over-the-air HD antennas, not satellite or cable service.
