> There is no doubt the biquad is a more exotic solution than what I tried a couple of years ago. Just a piece of coax with the correct impedance, I don't remember what impedance now of course, and a connector from altex for the wifi card. and an 11 ounce coffee can. The included link has a calculator for the location of the hole you need to drill or gouge out. I kept it simple by trimming back the center conductor insulation to the right length. If I recall about 1.2 inches. And then soldered the shield directly to the can. Here in Corpus my closest access point was about a half mile, and with obstrutions, but I could connect. Of course the biquad is much cooler!
sorry for the long reply I have been so wrapped up trying to get my gps
win sync with kismet, gpsdrive and google earth that I havent bothered
to check my email.
Success though milestone two is passed an I will conducting a passive
scan of the downtown area. hopefully I will have a nice kml file to
open up with google earth.
As for the antenna I will first build a couple of cantennas out of
pringles cans in the next couple of days before I try out the bi-quad.
Personally I think the bi-quad would look pretty cool on my roof.
as for the range of my war-driving antenna that I hacked to my lappy I
am picking up packets from about 4 to 5 blocks away.
by the way anyone have any info on on a series of ap called
