The problem, as I see it, would not only be signal strength, but also overcoming the curvature of the earth with suitably high antennae on both ends
This is a factor. The 125 mile / 200 km shot across America took a 6,000 ft (1,829m) peak at each end over a 125 mile long valley.
Most of AT&T's USA microwave network used 300 ft (90m) towers over 25-35 mile (40 - 56 km) hops or equivalents with terrain assistance.
