This is highly dependent on the campground. MANY do not subscribe to cable HD due to the added cost. They may provide only the analog channel lineup (lower 100 channels mostly).
At many campgrounds with cable (close to major cities) you will see the cable hooked up (for extended basic programming like TNT or CNN) and the antenna up (for switching to local network programming in HD like CBS, NBC, or ABC).
Switching between reception modes is as simple as pushing the power button on the antenna switcher and a re-scan of the channels.
