Have anyone tryed these adaptors? I have ALFA with AR9271 where the TX power is 13-18.With these I will get 22-28dbm. And besides the connection is with UTP cable and RJ45. http://dl.ubnt.com/datasheets/bulletm/BulletM_Ti_DS.pdf http://i.mt.lv/routerboard/files/Groove52_1374569972.pdf Both use Atheros,but Mikrotik has 600mhz CPU compare to ubiquiti-400 and it has 64mb of ram which is double than ubiquiti 32mb. p.s.I found one more similar which reach even 31dbm http://routerboard.com/RBMetal5SHPn
