41 KM (26 Miles) Achieved - Direct/single hop! (near-instant transmission & confirmation)

I will recreate this and document it better in the near future, probably with video. In summary, I was able to stand on the side of the road holding a small yagi antenna (the antenna was probably a total of 7' off the ground) and make direct contact with my home "base station" e-paper mini-node. This means 6 packets were exchanged directly via RF (no meshing).

The type of equipment used is described in the image. I have other fairly-inexpensive equipment already in my possession that I think will easily cover larger distances, and will be running more tests as the weather warms up.

There are no mountains or significant hills here, so this was across quite flat land. I really didn't expect it to work without me holding the antenna higher. The roof mounted antenna at my house is about 20 feet off the ground.
