Hi 2 frogs, yes that was my starting point but often charts dont express real world experiences
In addition I am willing to mix and match devices to get results meaning, its more important to get a setup where the temporary antenna is easy to align with the fixed site.
I should add the distance is now reduced to approx 1200m.
highpower fixed - highpower temp (hard to aim temp) (10,100, 1000)
highpower fixed - mediumpower temp (ave difficulty to aim temp) (10,100,1000)
highpower fixed - lowpower temp (easy to aim temp) (10,100)
medpwer - medpwr temp (easy to aim temp) (10,100,1000)
medpwer - lowpwer temp (easy to aim temp) 10,100)
lowpwr - lowpwer temp (easy to aim temp) (10/100)
Conclusion: I would probably procure the medpwer to medpwr solution.
From recent 60Hz results, it would be a no brainer in terms of throughput and lack of interference and I could host a local AP at the temp site if necessary.
However the aim and alignment setup scares the beejezus out of me.
I'd rather manage rats than software. Follow my advice at your own risk! (Sob & mkx forced me to write that!)
