Last I knew no one could say for sure how well the 3000's MU worked with the Mimosa Omni. So if you are depending on MU-MiMo to work you should probably look at the KPP omni made just for the 3000 and MU. Also, pretty sure ePMP beam forming can't work with any omni since ePMP / Cambium requires a special / separate, beam forming antenna to do beam forming for some reason.
