Does my new Springdale tt have a radio antenna?

I used to have a 2011 Springdale 266RLSSR and had zero reception from the factory Jensen radio. After removing the radio, I discovered that the Sherlocks at the factory left the antenna wire coiled in a little bundle just like it came from Jensen. I just stretched it out vertically against a wall corner and had perfect reception ever after. I had considered an outside antenna but found it unnecessary unless you are in the middle of nowhere.
