Tv at camp grounds

Hi, we are renting a seasonal for rest of this year, figure its best way to actually get the most use out of unit for remainder of season because of schedule, the camp ground we are staying at has nothing, I am sure that antenna that came on unit doesn't get great reception, I'm all for the away from electronic thing we are teaching the kids, that is till college football kicks off in September, what does everyone use, I have looked into the dish tailgater thing, but it keeps sounding like I just cant hook it in cable entry at back of trailer, any help would be appreciated...
