I am attempting to setup a 802.11b bridge between my location (siteA) down
the powerlines but off to the right NLOS (siteB) roughly 1 mile away. Now
their is nothing between the powerline and siteB except it is off the
powerlines to the right by about 20-40 feet. No trees, hills or any other
unforeseen obstacles other than I simply cant see it due to the location. I
guess the easy way to explain the setup is picture a L. I have successfully
been able to broadcast my signal in reverse from siteA down the powerline
even further than siteB but it was a strait shot and also was NLOS due to a
house being directly in front. This was using a 24db parabolic grid
antenna. My question and what I am trying to get my head around is if I
could get by with just a standard wireless router without any external addon
or booster antenna at siteB. Common sense tells me that even though its
shaped similar to a L as long as the signal coming off siteB is present at
the end of the powerline then I should be able to pick it up from the grid
antenna. I plan on trying it this weekend but I am hoping someone can
elaborate on this before I get my hopes up to much.

Poor planning on your part does not constitute an emergency on my part.
