I need to span 8 miles using the 1410 Bridge with integrated antenna. I configured the bridges in a lab and confirmed that they "talk". Taking them out to the span, the units didn't connect. So, I saved the configurations and placed the bridges in "install" mode. They connect! As soon as I reconfigure them they stop talking (either, one item at a time cfg or saved cfg file).
Site survey reported no interference and the path is Clear LOS. A 5.8GHz link was working on this span before (replacing with Cisco).
The only item I haven't checked was the distance configuration on the root bridge from 0 to 13KM.
