In my spare time I build and test various wifi designs found on the Internet. I am using this knowledge to build cheap and simple wifi hot-spots that can be setup with very little technical knowledge. I believe that wifi should be in all places people frequent. From the mall, the grocery store, to downtown areas, free wireless Internet should be everywhere.

Sector Antenna version 2 teardown
I decided to redesign the sector antenna backplate/reflector to make it more robust. As you can see the hot-glued antenna standouts were inadequate to deal with even transport vibrations. I have decided to use nylon screw anchors the next time. The main differences between this and version one are as follows. Most noticeable is the copper coating on the reflector assembly. I used copper gasket spray which can be purchased at automotive parts house. The second difference is the copper insulator at the center of the antenna element. A few other people have used this method, I found it was far superior for holding everything in place and aligned. There are no other modifications done.
