56mhz throughput data capacities vs 80mhz throughput data capacities is a significant factor. Plus can the AF11 do ACCP (Unless yo use 2 dishes or a custom combiner)? We had a link recently with only 80mhz channels available on vertical. Getting to 4096 QAM is not easy on longer links (Probably anything over 4-5miles) IMO. I am a huge fan of Ceragon IP/20/Cambium PTP820 very reliable radios with a great feature set. The only thing they are missing is a SFP+ port (Which I believe is coming on a new version)
