I want to create a full duplex backhaul setup that is capable of achieving 20-30M over 11miles. I have clear line of sight. I was thinking of using RB-433AH on each side with 2 R52Hn cards on each side. I am assuming i would have to have 2 sets of antenna's one for corresponding TX and RX on each side. I also assume that i would run them on separate polarities, but even with that, how far apart should these antenna's be mounted? I want to use 5.8hz band. my questions are this.. are my assumptions correct, and can this hardware do what i want?
