I still think your best bet it to use 2.4GHz WiFi gear linked "house to house"
with cheap dish antennas on towers. Get that amateur radio license and you
can legally run enough power that you'll easily make the distances, and no one
will question why it is you're buying, e.g., 10W 2.4GHz amplifiers. Those
dish antennas are probably going to be a lot cheaper than a bunch of Yagis
anyway...

The FCC allows 4 watts EIRP for fixed point to point WiFi links. At 2.4gHz
this is a lot of power, usually created by focusing the output of a
regular router or similar device with a small dish or Yagi.

For example, the well publicised "Pringles Can" antenna can be easily
modified to put out that much from a 100mw source. You need line of site,
but if you figure a two routers, antennas, wires, etc can be purchased in the
U.S. for less than $200, you can set up a whole relay system.

The latency will be much too high for VoIP and video conferencing, but
websurfing and file downloading would be fine.
