Thank you for reply.
It's actually not Aruba's own antenna. I think that's okay, right?
I know I only have to connect two connectors but what I actually was thinking was that in aruba ap-104 datasheet it says about antennas:
AP-104 and IAP-104: Four RP-SMA connectors for external
single-band antennas
I don't know if this antenna is going to work because it's "dual-band antenna". All 6 connectors of the antenna can all be use either 2.4 or 5.0.
Does anyone know the answer?
