Fixing AX-11000 broken antenna?

[Kashif Tasneem]

Hi. Bottom part of one of the antennas broke. Specifically the screw part. Please see the below images:

I have antennas from my old broken AC-5300 router. Can I remove the screw part from those antennas and add it to this one? Is this possible?

Same thing happened to me. Take some silicone and voila
