The only real difference in the RV with digital TV which I must admit took me awhile to figure out is that you can't just put the antenna up and give it a twirl and get the stations. You have to "slowly" turn it and "tweak" the antenna dial to catch the signal unlike the old analog signals.
BTW:a little OT:: I just bought another TV for the RV and it won't scan the UHF channels.On the scan menu it says TV not set to scan UHF. Can't find anything in the menu to turn that function on. Anyone else have this problem??
