B One 5G antenna question

The B One has 4 antenna ports on it.
Can I run a 2X2 Mimo Omni and a 2X2 Directional?

Where we camp the towers are far away and the directional is needed for good download speeds. But for some reason that tower gives HORRIBLE upload speeds and our Omni antenna gets better uploads. But when used alone in our Transit duo it get pathetic uploads.

Would the B One 5g combine then and let me get the best of both?

Thanks
