Tilt radar of SPAA

Hey there!
Today I saw a ItO 90M with a tilted radar dish. It wasn’t for folded all the way, but it wasn’t straight up either (just to be clear).
So looked through the controlls and there is indeed an option to bind keys for this, but I can’t get it to work and either the ItO, the Pantsir, or any other SPAA I have.
Which vehicles support this feature and how do I use it properly?

Radar antena orientation is for planes only. If you see a tilted antena on a ground vehicle it is a visual bug.

I had a feeling that it was a bug, but why are the controls under “ground vehicles” then?

Maybe aviable later …
