Yeah, they have added another one on the rear platform, besides the elevator and there are some small antennas added recently.
Mostlikely, is for drone operations, loosely integrated to TCG Anadolu by Baykar (of course funded through acquisition channels).
So instead of using organic, on-board sensors and datalinks, satcoms; It seems Baykar has been installing their own parallel systems on board.
Specifically that forward position, which is also where Ground Control Station of Baykar is located at, goes through high accelerations and vibrations on high seas (slamming, et al. ). That satcom will hardly survive after an Atlantic and Mediterrenean trip.
There are new additions on the frontside of island, on starboard side and the same pattern exists on the sternside of the island, on the port side.
There are at least 8 new small, and 2 large antennas installed for drone operarions, by Baykar.
