   As I told Rod Speed, and as I tell him again, your information trumps mine.   
   I don't mind correction, as the correct answer is all that matters.

   I was afraid of that, which is a critical error on my part, but I didn't   
   look up the specs for the horizontal and vertical beam width at 150 feet.   
      
   This should prove to Rod Speed that your observations trump mine!

   This is an important point that the antenna needs to be relatively low   
   gain, just to paint the entire house.   
      
   Wouldn't it work though, even with a nanobeam or powerbeam, if there was a   
   second matching antenna on the outside wall of the neighbor's house at 150   
   feet away?

   I concur. When I have about 12dBm between the noise level and the received   
   signal, I generally connect. This is better than that, by a lot (if you   
   assume the noise is in the -90dBm range).
