Two to three hundred meters is trivial for line-of-sight directionals, as
many have pointed out.

That range is a bit more difficult to do with omnis.  Just how much do
you plan to move?  If it's within a certain area, sector antennas are
really the way to go.  You get a pretty serious signal over a wide area.
True omnis can get up there, but not quite what a sector can do.  You'll
definately need one on the outside of your location, though.

I haven't yet, but I just got my Linksys card installed with an=20
external antenna.  Planning on getting an antenna for the roof before
too long.
