No, no. It's not that.
Mod for a new, properly functioning, radar antennas are spread out in several files: Animations, Cfg, Interior, Library, Objects and Submarine. I was in "Objects" is like: "turm7c_2_hd.dat". And in this file, when opened in S3D, is a whole list of weird "ingredients". I do not know who is responsible for rotating radar antenna.
And this is a problem ...
