Hi, I'm confused about the antennas for this AP. Both the manual ans SolutionBuilder say that these antennas ML-2452-APA2-01 (RP-SMA-M) and ML-2499-APA2-01 (RP-BNC-M) are compatible with AP621 and AP6521. There is not even a note saying which adapter has to be used. Trying to check in the Antenna Guide Ver. 1.9 I can see that ML-2452-APA2-01 works equally for AP7131, AP650, AP651 and AP6521. Do we have an updated antenna guide ? Regards, Gustavo,
