Wireless Joint

Hey yall, I currently have a pair of wideband directional mimos set up on my mofi 4500. Im expecting my mofi 5500 em7690 in any day now, and since it has 4x4 mimo I figure I might as well plan on setting up another set of mimo antennas.

My mimo directionals are set up on a single pole 1 above the other, 3 feet apart and tilted at 45 degrees from each other. Could I add 2 more directionals to the pole and be able to have 4x4 mimo? I worry that too much right there together would cause interference with each other. Or, could I run a 2x2 flat panel along with the directionals and not have a range /reception problem? I had thought of adding a pair of Omnidirectionals but I dont think that would help much with range and possible interference with the directionals.....

any suggestions?

Skip the omnis. The flat 2x2 would work best, but another two of the same antennas would create a full matching pair. You can polarize the antennas, tilting 45 degrees from vertical (opposite each other) right next to each other. Then place the second pair a foot or three so away in the same configuration.
They don't all have to be spaced far apart to be functionally clean and strong signal.

Ty for your help Didney, I really appreciate it. Finally had time today to get up on the roof and get it all situated,. I wasnt able to put them exactly side by side on the pole but I have 1 slightly lower than its partner, one tilted 45 to the right and the other 45 to the left, with the second set the same way about 2 or 3 feet below. I think its working out pretty good.
