I feel like Siklu let you down in some horrible way Eric.
Siklu has their link budget info right on their datasheets. Need the extra TX power, go with one of the newer radios. 700 – 5dBm 1200 – 7dBm 2200 – 11dBm 2500 – 18.5dBm 5500 – 16dBm (what’s this ;-) http://lbc.siklu.com/ Back when they only had the 1200 which has that +7dBm TX power is certainly limited the radio, and many people mis-deployed it under guidelines they would use for BridgeWave. But that is simply poor engineering. But also to put into context – lowest average rain rate in North America is typically 25 mm/hr for 99.99% operation. That is 10dB of fade at 1km at 99.99% availability. So your argument is true – that is 1km of distance your leaving on the table. See the chart below I made many moons ago. Every 60GHz/80GHz (regardless of vendor) I have engineered performs to spec. Engineer, engineer, engineer.

There's a reason why some of the more expensive 80 GHz products (Moseley/Remec/Bridgewave), SIAE, NEC etc are more costly, that's because of the total link budget you can achieve with +18 Tx power going into a 52dBi gain 60cm antenna.
