I am trying to extend our network using RB532a with 5GHz bachaul and a 2.4ghz broadcast. The links will be about 6 miles from point to point. The towers are 200' and 120' no obstructions. I will be using two 18" 5ghz solid dish for backhaul. And a 18dbi omni for broadcast. Would a XR2 and XR5 be to much for this. I would like to cover about five square miles from 2.4 broadcast. Ideas?
