Subject: [MLB-WIRELESS] Highly Directional Antennas?


I have been looking into a way to build a highly directional Antenna for use 
of pinpointing where AP's are. Accurate enough so that I can confirm that 
the AP belongs to a certain house rather than 1 of 3 neighbouring houses. I 
can use my Omni to find the general area, just need something to pinpoint.

I have built a few antennas in the past using asian cookware and wireless 
USB dongles which worked very well but the signal is too wide. I considerd 
building a cantenna however with some basic tests I found that the signal 
tends to rebound (i was getting better signals bouncing it off objects 
rather than pointing it in the direction the AP is in which was through 
walls).

Can anyone suggest a way to build a highly directional antenna?
