Re: These Ducks Quack !!! OK, I tried the wet-11 antenna, but it did not fair to well, so I rebuilt my first antenna to remove some of the un even curve. Take a look at what netstumbler reported as my signal to noise graph. What I did was start with my first antenna enhancer, to none, then to the second wet-11 and back to the first. I think the first is giving much better signal.
On a side note, i noticed that my laptop wireless card had a firmware update that I had not applied. That also made a world of difference to the link quality. Did not change the signal though. So if you have a USR pcimca card, you might want to see if there is newer firmware.
Thanks! This was a fun experiment!

Nice work. Yes the dipole reflector is the best one for your setup. Reading your graph, it looks like the extra care with the first antenna netted you about 2 dB of gain.
That's nearly twice as good. 8 dB of gain is half as much gain as 11 dB of gain. I say the little antenna is a dipole most surely.
Take that same reflector and put it on a WET-11 and it will perform badly, take that WET-11 template you build and it will perform about as good as the other does with a dipole, you are getting about 10 or 12 dB of gain with the first antenna. Nothing to sneeze at and the workmanship is good.
Nice work.
