I think the HFDF it on the other arm of the rear mast, portside, in black. Is it possible that it is something on the roof of the building, rather than it being on the ship?

For comparison some other pics of ENS El Suez and Abu Qir.

Guess there really is something on starboard side...., which is NOT present in the Spanish and Moroccan ships.
