I have users on 2.4GHz at a range of 30+ miles with clear LoS.
On 5.8GHz I have links over 25 miles with clear LoS.
Just wish I could get that 900MHz stuff to work better.

can see your plots, too)
It is flat here, but the trees are the problem for RF.
Do I understand the last plot correctly: that ignoring trees, a 2.4GHz
signal would work for ~12 miles? Amazing.
I feel lucky when I can get a 2.4 customer connected at better than
-80, and they are usually within a mile of a grain leg.

You were right. Without considering trees, a 26 meter high tower (grain
leg) on each end would do it.
I used a 200 mw radio and a 23 dBi panel antenna (like the Deliberant
1A23
self contained radio).
Of course the Alvarion units would be the choice if you had the $$.

Just a quick demo of some of the power of Radiomobile
BTW- I was amazed at what you flatlanders can do on 2.4!
