'96 Airstream Classic 36’ TV Motorhome

[PeterK]

Hi Folks,
I posted this in the motorhome section and I was re directed to here.
I am new to this coach and I cannot figure out the TV. So it has two TV’s. One in the front dash and one in the back bedroom on a shelf.
Neither are digital so of course they will not pick up signal. The coach has a TV antenna which I understand will pick up digital signal.
I cannot figure out where the antenna signal enters the coach and attaches to the TV. I am assuming that I will need a converter between the antenna and the TV.
Will I have to yank the TV out of the and try and Mcgyver the converter in behind the TV some how?

I see a coax cable outlet, that is powered,on the side cabinet between the two cocktail chairs but does not makes sense that you have to run a separate coax cable across the floor to the TV. I think the coax system is behind the walls.
Any ideas?
