Link PtP

Hello Guys,

I have to make a point to point connection between two buildings at a distance
of 6Km I’m using forms Ubiquiti ST71-15 and dual feed antennas, I
wondering what the best configuration to be given to radio or
better in what way should make them work to get the most
performance?

I thought about this

Site A (Mode = Radio Station)
Site B (Radio Mode = Bridge Ap)

Thanks
