Thanks for your responses. I guess I was mistaken and maybe more confused after both posts. I apologize if the next few questions are dumb.
From the Spec sheet, I understand that the antenna is a dual band antenna. To quote the sheet ".....The Aruba AP-ANT-90 is a dual-band, spatial diversity....." . Am I misunderstanding this? And if it is dual band and only has two connectors in different bands and MIMO radios must have all chains connected does this not also imply that I require two Ant-90's? I must be overthinking this or simply not getting it. Please advise.
Also, what If i do not desire dual band coverage? What If i only want 2.4Ghz? The implementation is a warehouse, 50ft tall hence the question.
thanks again for your time and expertise,
