It all depends on where you are and what's happening. For me, we got a big improvement: real dodgy reception of WFMY (CBS), WXII (NBC) and WXLV (ABC), just about watchable WGHP (Fox) and WUNC/WUNL (PBS), fantastic WGPX (Ion), WGCWG (CW) and WMYV (MyTv). Sometimes we even got Univision. When we got our digital box, we got good reception of everything except PBS and NBC - NBC we literally will need to get an outdoor antenna for, and PBS is hit-and-miss - some days it's good, some days it breaks up. The others just boom on in.
Now Inchworm, if your DU profile is correct then antennaweb.org has bad news for you. I did just a zip code look up for Lansing, NC and got "no tv services offered in this area" at all - not even using a high gain, outdoor, rotating, pre-amplified antenna. I thought funny, because UNC-TV has translators scattered throughout the mountain communities, and yes, there is one near you: W25AY, licensed to Jefferson, NC. According to the FCC (
http://www.fcc.gov/fcc-bin/audio2?x=tvq.html) the signal is supposed to cover Lansing. I then decided to double check antennaweb.org - I picked out some real estate for sale in Lansing and plugged that in... lo and behold you do get two TV stations: UNC-TV and NBC - WCYB out of Bristol, VA. The latter is apparently only possible with an outdoor, high gain, directional pre-amplified antenna.
Now if you're getting WCYB on Channel 5 out of Bristol then... you should in theory be able to receive WKPT on channel 19. Its transmitter isn't too far away, about equal average output power and is supposed to cover your area well. However WKPT is broadcasting in low power digital still so no hope of getting a signal from them yet.
As for digital TV... well it's going to be interesting. WCYB is broadcasting in digital on channel 28 - that's UHF - and UHF signals have a different nature to them compared to VHF. Now WCYB will be moving back to Channel 5 - so if you're getting channel 5 now in analog, you will definitely get it in digital but you might have to wait until analog switch off to get it as WCYB cannot broadcast in digital and analog on the same channel at the same time. As for that UNC-TV translator in Jefferson, if you somehow figure out how to receive it you may well be able to still receive it after digital switch off: UNC-TV hasn't mentioned any plans to digitize its translators (save one which its converting to a "full power" digital-only station) and it's only full power stations that are affected by the switch over from analog to digital. So for now, I'm going to stick my neck out on the line: if all you get is channel 5 then you might well get nothing and if you get something then all you're going to get is WCYB and its subchannel. (so you'll get NBC and the CW)
In any case it's definitely worth your while getting the set top boxes. I might be wrong, and you might move into an area where there's better TV coverage. You might equip yourself with a better antenna (I don't know what you're using right now). Failing that if cable is available, take their absolute basic package. That way you'll at least get UNC-TV in the clear plus all the other major broadcast networks. Other than that, then the only two other choices are satellite or no TV at all.
