This is for those starting out in wardriving and wifi hacking. A powerful setup at only $14.99 with a 9dbi antenna. You could use a program like WiFi-Where if you have an iPhone to plot networks on a map or in an excel table. This will save you buying an bluetooth or USB GPS data logger. Due to the nature of the the design you could plot this device on the top of your car with an adhesive pad. This is a serious kit for serious people and likely to be illegal in some countries. We recommend that you use BackTrack 5R2, latest compat-wireless drivers, increase TX power beyond your regulatory domain and install it onto a hard drive or virtual machine (VM) environment. I will add other sources and suppliers when I have a chance.Adapter: GSKy StarBase (RTL8187L) with 9dBi Dipole Antenna - Login or Signup to view links / downloads $15 USD(currency converter left side, bottom bar)Login or Signup to view links / downloads Price is an estimation only and does not take into account postage.
