Solution
I will agree on the need for clear line of sight but the technology has gotten MUCH simpler and cheaper compared to the days when people used antennas and hacked routers to work on them.

The solution I like the most is ubiquiti airgrid system. These can easily go 1/2 mile they will go much farther but you need towers to get the 20km they claim. I am not real sure I believe 20km but I have used them at close to 1/2 mile distances with no issues. These units cost $75 each and to your equipment they pretty much appear as a ethernet cable.

You can also use engenius enh200 if you want a more compact device.

These are pretty easy to install. You mount them on a pole as high as you can get and they get the power over a ethernet cable...
This can be done, but with not with equipment you can get off of best buy or walmart shelfs.

You would need to get routers with external antenna ports, and securely mount a yagi directional antenna on the roof of each house, and this is completely requiring that the antennas that they have line of sight to each other. In short, if you both cant stand on the roof of the houses and see each other with a good pair of binoculars then you do not have line of sight.

You will also need to configure the routers appropriately and possibly need to flash the routers with dd-wrt.


To do this right at all it is a $300-500 endeavor and requires someone with at least mid level computer abilities.
This is using home/small office grade equipment and not commercial grade (a single dual radio router can go for $500-2000 alone)
If this is something you want to pursue we can take it further, but anything less then this will be 15% functional to completely useless.

You key problem though is you must be able to see between the locations with no trees in the way. You technically need to be about 10ft over the top of the trees but it will likely work at these short distance as long as you can clear see the antenna on both ends.
