Just two degrees off? Can they not wiggle the antenna a bit around [1] just as in the old days when you had to hold the TV antenna a bit above the TV to see anything but noise?

[1] Joking aside, they obviously can not, Voyager is missing the Earth by 4.5 AE. How wide is the beam, how precisely do they have to aim the antenna to maintain communication?

The beam width is 0.65° at x-band. If it's off pointed by 0.5°, the signal will be 7 dB lower (which in this case, is a lot).
