I happen to live in the bottom part of a small valley which is bad for ADS-B reception. The good thing is, my neighbour has a barn almost on top of the ridge and I would have direct line of sight to it (250 m distance). So the idea is to move my site to this barn in order to get better reception. However I would need a way to transfer the data to my house. A 3g modem is not an option since it is very expensive here.
So what’s the best way to establish a point-to point connection for this distance and bandwidth (~3 kb/s)? It should be weather-proof, stork-proof and affordable.
