It also has a 1.3m according to the literature ..plus three 2.6m dishes. Therefore 4 antennas yet the info on the beams so far refers to 3 beams for Europe. The fourth antenna is KA band I assume???
The antenna details in the "launch_kit_203_1_2.pdf" document is different from the info on the astrium page:

"The spacecraft will have three deployable antennas
with diameter up to 2.6m and one top-floor steerable 1.3m antenna."
One of the three deployable antennas appears to be smaller than the other two (the one that is almost hidden in the picture)
There's also a better view of this in the video at 1:15.
