Well, I'm becoming familiar with my new 2012 2720SL, and liking it.
I had an issue with no signal on the outside curb side, but found that
was due to somebody at some time stuffing the floor cabinet and breaking
the coax connector near the top of the storage area. Used standard pliers
to refresh the coax connection, typical monkeyriggin', but the signal is good.
I affixed a plastic cup over the connection to help protect it.
Anyway, it has the mentioned 3 inside to tv, 1 curb to tv, and 1 street input.
Now, they work when I attach an antenna to the street input jack, and that
is good.
A Winegard brochure came with the documentation, and it shows the bat
antenna, which I believe is for the radio, along with the amp button. I do
not see any TV antennas on the camper. Brochure shows lots of TV antennas.
So, is that all there is? Or is there a TV antenna somewhere? Ain't no crank
in the roof. Ain't no roof repairs.
In some areas, especially where there are pop-up storms, a TV is good for
weather forecasts in real-time.
