yagi antenna and wifi antenna

Once this was up and running, we looked at the design, and of course
speculated about ways to optimize it. While a directional antenna showing
between 12 and 15db gain is impressive, it's also pretty large, physically.
We realized that, if we were careful, we could fit a full wavelength inside
the Pringles can itself (at a reduced total gain), but make the entire
antenna much more compact.

In about 45 minutes, we had the collector rod built, the locknuts on, and
the whole thing in place. The result: A Pringles can that pulls about 12db!
