Will Winegard Traveler work w/ existing cables?

The reason I asked is because my new MH is in the shop now getting a dome installed. HD isn't that important to me and when I take my grand kids, they like to watch tv to keep them occupied when we're traveling. I had a dome in the one I traded in on this one and it worked just fine for the 5 yrs I had it. When I'm out enjoying the MH watching tv isn't a priority. I can do that at home.

Thanks for the response.
