I have a customer that wants to replace about 500 - 700 Cisco Access Points with AP7131's.   Many of them are located outdoors in Nema boxes with high gain 2.4 antennas.  In the outdoor setting we will be meshing the AP7131 on N and will require new antennas.  But all data will be on 2.4.  The customer is asking if there is any way he can use his current 2.4 antennas.
