First Mikrotik RouterBOARD with MIMO 4x4 support ?

I bought Mikrotik RB912UAG-OUT, I open it to check that it is the same board as standard 912UAG and I’m very surprised because there is 4x external antenna connectors (2x RP SMA, 2x MMCX). What does it mean ? I saw some MIMO 4x4 antennas with sign Made for Mikrotik: http://www.wireless-instruments.com/en/produkty/15/56/antennas-5-ghz/mimo/directional/wibox-pa-d4m5-20hvx.html, but I never heard about even MIMO 3x3 Mikrotik RouterBOARD. May be somebody know more about it. Photo of my board:

No, you can use RSMA or MMCX. It have two chains

EDIT:

See posts below.

those are standard mmcx connectors an might be connected in parallel with SMA ones. But sure is not an 4x4 mimo radio.

Thomas, in this case, they are actually MMCX, but the radio has only two chains. You can use either MMCX or RPSMA

Thanks for the clarification :slight_smile:

As we discuss about this radio… do MT plan to develop 3x3 and 4x4 radios ?
