Thanks Mike.

Given that its not 90 degrees ;-), I figure I'll probably add on an
omni-directional antenna - the homes it this area are spread over about 200
degrees with only a couple of places out side of this. What I really would
like for this access point is about a 3-4 km range; more would be nice but
not an absolute must.
