What does shark fin antenna do on 2026 bighorn?

[raoul_duke]

I really would like to remove the shark fin for clearance on my slide-in camper.

It is a 2026 bighorn with level 2 and the small (8.4”?) screen no navigation. I rarely use am/fm and don’t use satellite radio. I also do not use or subscribe to the RAM app.

I assume it is AM/FM and what else would I lose if I ditch it? I read somewhere it is also cellular but cellular for what application?

Thanks
