What's the antenna on my roof?

I've never owned this new (2013) of an RV, so am curious what the antenna is on my roof? Seems to have a single RCA plug coming out of ceiling for an antenna feed...

Posting pix will make all the difference. What you refer to as 'RCA' has been mistaken as what is actually a 'Motorola' (and a newer one I don't remember) that is an AM/FM broadcast antenna connector.
