One thing that can happen in a campground..
Background: As a Ham Radio operator I like to check into a few nets on a couple of ham bands, these are far removed from TV band (Well most of them are, I ahve a few I work that are mixed in with the TV bands) and just now for example, the noise level is, as my radio is set up, below the meter's minimum display threshold (in short VERY LOW). ON the other hand a new neighbor can pull in or a long term lease arrives and turns on his whatever and the noise level jumps up to the point where it threatens to overload said meter. (That is the "Can't hear myself" level) Many RV's are just a bit on the noisy side of complying with FCC Part 15, Suspect devices include Inverters (MSW are very bad at this) Converters, Refrigerator controls, Some of the original Winegard antennas (None of which should be in service any more, they completed the recall) and more. Some of these noise sources can go all the way through the TV band into the Satellite bands and beyond.
NOTE: I see them on teh VHF/UHF meter too on occason (The radio has two signal meters, one is exclusively VHF/UHF, bands, the other is not)
But if you get a noisy neighbor what was good can be insta-crap signal wise.
Also, I've found if a station is "on the edge" just a small change in location might make a difference, A tree limb may be blocking a bit,
Finally, though TV studios and "broadcast houses" may be scattered all over there bent and gone......
Quite often the transmitters are parked one atop the other real-estate wise, Usually on the highest hunk of rock in the neighborhood (A mountain) if there is one around.
