Which antenna for max br1 mini cat6?

Cool I was pretty sure directional was for me but everyone kept saying you need a perfect line of site like over the water or something so I wasn’t sure with the trees.

My only other question is whether or not I’m supposed to use a directional mimo antenna or two seperate directional antennas? and which one?

The only thing I’ve found from looking on here is the XPOL-2. thanks!
