MIMO vs Dual Nstream

Hi
we recently started a implementation of a mikrotik network, and would like to know what do you think, which is the best? MIMO or Dual Nstream??

maybe a small picture of what we have and need
we need serious video streaming and about 4 systems running on one backbone
backbone has 4 towers max distance about 5 - 7KM
very high up no buildings.
26db grids want to change to dishes dual polarized for Mimo
1M lmr400 cables
433routerboards
R52hn rf cards

any suggestions?

Hi Snakez,

which type of MiMO you want use? Typically you wouldn’t get any improvement by using MIMO if you don’t have reflections. (you say high buildings LoS etc.)
