And don't just think of line-of-sight but also take the Fresnel-Zone* into
account because every dB counts. You might want to install WiMax, which is
designed to cover distances of up to 50km instead of being bent on WiFi. Using
high-gain directional antennas makes your installation illegal in most
countries unless you are a licensed radio amateur. But even then you need to
stay within the assigned frequenies for amateur radio and you are not allowed
