I'm looking to deploy IAP-175's with the Ant-90 antenna. Given that the 175 has 4 antenna's should I plan for "2" Ant-90 antenna's for every IAP-175 ?

It depends on how you are deploying your coverage. The AP-ANT-90 is a downtilt omnidirectional antenna, so that means it is suitable for mounting 30 to 40 feet above in a warehouse where you need coverage on the floor. It has two connectors, so you would only need a single AP-ANT-90 antenna for each band. So if you only want 2.4ghz coverage, you will only need one AP-ANT-90 antenna. If you want both 2.4ghz and 5ghz coverage, you will need two AP-ANT-90 antennas. That is IF that is the antenna you need for that application...

Just to be extra clear....Colin is not saying that you can use one (1) ANT-90 and connect a pigtail to each radio (leaving the other chain unconnected).
MIMO radios must have all chains connected. So if you want dual band coverage, you need two (2) ANT-90s.
Also, ANT-90 is perfectly good higher than 30-40ft (10-15m). In fact, the antenna was originally developed for seaport high mast lighting systems. We have them deployed as high as 50 meters and they work great.

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,
