MIMO antenna spacing?

[mscherting]

Any tips or hard rules on spacing external 2.4 & 5Ghz MIMO antennas?

I've been pulled into a project utilizing 1262 N APs and a proposal to use Cisco AIR-ANT1728 and  AIR-ANT5160V-R antennas.  If these antennas are used what spacing should be used between elements of the arrays?
