What Larry said.. To the antenna, it's all Radio.. But there is a difference between say VHF low and UHF,, big difference in fact... More later:
To the TELEVISION it matters if it is HD, SD, Digital, QAM or Didital ATSC Not all televisions do "All of the above)
Older "Squarish" TV's. both flat screen and CRT, likely do not do ATSC (Digital over the air broadcast)
Modern "Wide screen" TV's. do, in fact it is a requirement for type acceptcance
ELEMENT TV's (the only TV made in the United States) do not do QAM (digital cable)
All do NTSC (Analog if you can still find a signal)
So if you have an older TV you will need "Some kind of convertert" (Digital television converter) if you are hooked to a cable system that is encrypted. or have a tv that like the Element does not do digital cable. You may need a box from the cable company.
And if you have a modern Wide Screen, say Jenson, Sony, Toshiba, Dynex (What I'm watching) Or Samsung, to name just a few.. You need to follow instruction (Set source type and then scan channels)
Now the antenna
There are many RV antennas.. one is kind of a "Flying Saucer' Round, omni (in fact two are) The most common "Flying saucer" is a winegard Roadstar, omni, and I give it a strong bronx cheer.. It's junk.
Moving up we have the JACK from King controls ALso the rare directional flying saucer (I've nto seen it in RV stores... Just Radio Shack,, once saw one cut-away (With the covers removed,,Kind of compact really works)
Moving up we have Winegard Sensar line (Batwing) Top of this line is the Sensar IV,
Sensar II and III can be improved by adding the WINGMAN which is a UHF director array (Fancy name means it improves UHF performance in case you wonder).
And adding the SENSAR PRO inside the RV (Replaces the wall plate or can be installed between antenna and a box of many buttons (Matrix switch) gives you the best RV TV antenna system made..
What I'm using to feed my Dynex just now.
