This is a somewhat complex question and in part depends on where you are parked.
So here goes.
Over the air Broadcast TV.. (How I did it usually) advantages It is FREE
Disadvantages. Not all parks are in "Coverage Areas"
THe winegard Sensar IV crank up with built in wingman.. Coupled with the Winegard Sensar PRO wall plate instead of the default one.. Is rather hard to beat.
In fact I do not think there is a better RV tv antenna
have a Sensar III add the wingman
Cable TV Some parks have it and if they got it.. BEST by all standards
Satellite TV.. Depending on your antenna you may be limited (more in a bit) and you have to set up ground mount antennas every time Roof top antennas do not work if you are parked under the Evil Signal Eating Tree. (Thank you peanuts for the Kite Eating Tree).
Internet: OUCH that eats bandwidth. Now if you have Unlimited and a good signal in the campground. GO 4 IT... but many campgrounds the Cell signal is iffy and if you stream off the campground wi-fi.... Not good Well many campgrounds will throttle you and in other campgrounds your fellow campers just might (in a different way) .
How I did it
I had TWO single channel analog DVR's very programmable and very "Chatty" that is they shared files I could program a show to record on #1 from #2 or the other way around or on either of them from this laptop. Alas that company is no more. They controlled a couple of ATSC-NTSC coverters (Digital to analog) So I could download a program guide from Signals Direct.. Geed the .xml file to my software which did the needed edits to send the channel numbers and sub numbers to the DVR's and from there to the adapters and it recorded for later watching 2 shows could be recorded while I watched a 3rd (And wife a 4th) on the TV direct. Very nice.
Alas that's the one thing I miss most here in my apartment.. it's not in a good coverage area so I'm stuck with cable.
Home was where I park it. but alas the.
