I was told in the US the output was much higher. I have seen
presentations (http://www.nluug.nl/events/sane2000/daily/24/dijker.html)
from a wireless local-loop provider (Netrack) in the mountians (in
Colorado?). They use one omnidirectonal antenna with the endpoints using
flat directional antennas and they claimed to reach several miles.
And in the presentation was mentioned these distances wouldn't be
possible in Europe.
