Sure, but I wound't use three cards on the same band, on the same board. You will be interfering with yourself. You would be better off to use three 711UA-2HnD in separate cases.

I have 433 board with 3x high power dbii pro50 cards no problems here. I am sure there is a little RF leakage around the cards but does not seem to be enough to cause significant problem. They are spaced at 5260,5700 and 5580 ghz. 30cm good quality mmcx pigtails.

At 2.4GHz you will have much more self interference than at 5GHz, although I haven't tried it with DBII cards with MMCX.
I can vouch for a 30-40dB difference on self interference going from an R52H w/ufl vs XR5 and MMCX.
