Unfortunately MikroTik has received faulty RB2011UAS-2HnD-IN enclosures from their supplier. Those cases have incorrect position of mounting holes for indoor antennas with very high risk of breaking off MMCX connector, situated on the board.
Due to this, we had to order new batch of enclosures from MikroTik, and when those arrive in September, we will offer them free of charge to our customers. This issue will
delay all shipments of RB2011UAS-2HnD-IN for ~6 weeks.
