No.
MSR and IAP run different operating systems.
You should use MSR2000 instead of IAP175, you can configure on radio for mesh backhaul and one for client access.
Also, you cannot use all four radios on MSR4000 in 5GHz band, because you must have 40MHz separation of center frequencies. So you can use channels 149, 157 and 165. The 4th radio usually is in 2.4GHz.
So you would use two MSR2000 on the head end to achieve your goal. One AP can use 149 and 157, and the other AP can use 153 and 161.
You want ANT-2x2-5314 for the backhaul antenna and ANT-2x2-2005 for access.
