New Windshield: w/antenna vs without antenna

[amagalla]

I have a 2003 Boxster S, and I need to have the windshield replaced. My understanding with the S model (I've never had anything else so I wouldn't know the difference) has the titanium colored trim, and the top of the window is tinted green.

One question that threw me for a loop is the installer asked if it was a non-antenna or with the antenna version. How would I be able to tell. I thought that all the Boxters came with the antenna in the windshield.

Thanks for your help.
