Very good question ( and I wish I had an answer )
In short and old analog signal that you did get that were watchable before without trouble should be now perfect in digital
This is close, but needs some refinement.
Most of the new digital stations in the US are on UHF frequencies, so if you got good UHF reception before, you should be okay for a lot of digital stations.
Before I go on I have to explain something. When digital stations first appeared, their names, even their channel names, were made to look like their old names so we ignorant masses would not have to cope with too much change at once. However, their actual operating frequencies changed in many cases. For instance, here in Los Angeles, KCBS Channel 2 became KCBS Channel 2.1, but actually was broadcast on UHF Channel 36. To make things a bit less confusing, it's good to refer to channel numbers as, for instance, 2.1, but refer to frequencies by their real original channel number.
www.antennaweb.org refers to this as the "RF Channel," which is accurate.
Moving on, some markets have channels in the range of 7 - 13. Before the transition, all digital channels here were on UHF RF frequencies, but now 7.1, 9.1, 11.1 and 13.1 are on their original RF Frequencies 7, 9, 11 and 13.
If that's the case where you live, you'll need an antenna that can get these channels, called High Band VHF.
I think there are even a few Low Band VHF stations around, on RF channels 2, 3, 4, 5, or 7. Again, you need to know the RF channel for your local stations.
In the US, this can be found at
www.antennaweb.org, and
www.tvfool.com has much more information.
