Ron, You understand correctly, and answered the question Re: antenna connection. My unit is a 2015 and in addition to what you described, has a one each, red, yellow and white (what I call RCA) male jacks on approximately 3' long cord that are installed and disappear in the space between the double wall. I suspect that those would be to connect the factory installed dvd player to the TV mounted on shirt closet. On a different note, since you have the 19" mounted, would you have preferred to have something larger mounted or would it have too much of a "in your face" presentation?
