I couldnīt find original pictures of the Blyskawica with radar antennas fitted. Maybe they have been removed from the pictures. Today it still/again has the 290/291 aerial.

In the meantime, i found a great internet site from a polish expert about the radar equipment aboard german uboats. Itīs really worth to take a look on it:
