Why cars with solid roof have another antenna?

Was just looking at some pictures and saw that all the cars with a solid have another antenna? Are cars with pano roof missing something?

No the cars with pano roof have their antenna in the bump on the top of the tailgate spoiler, I suspect that cars with the solid roof don't have any antennae in the tailgate spoiler. I was also told the other day that as well as the satnav the phone, TV and radio antennae are all in the spoiler

I thought the same thing but it seems like they have both

P.S. seems like pures have a new option with fog lights
