Step 6: .. & Final look ...

Finished antenna w/o a stand looks like this from backside (pointed to the AP with vertical signal polarization) on a first slide and frontside view on the next ...

Inner side view of the mounted Key, clearly shows its offset position, if carefully checked. The front tip of a plastic Key enclosure is pushed/situated 37mm (for this particular Key) from inner bottom of a tetrapak, which is practically antenna back "metal" reflector; so the Keys chip antenna hot tip is situated right in the middle & 30-31mm (wifi 1/4-WL) away from the bottom of the finished enhancer, which represents a WaveGuide 1,5-WL long at higher wifi channels ...

The antenna is quite directional & extends Keys range for about 4 times or a bit more in open non-obstacled distance/view ! The range of this basic setup can be extended even further ... but about that in a maybe new Instructable some day later ! ...

doesn't this have to be metal to enhance any sort of signal? This is a type of cantenna isn't it?
Yes, there is ! That cardboard material for tetrapacks is multilayered stuff with embedded aluminum foil inside (that´s why tetrapacks are a real enviromental threat, of which nobody says anything, almost impossible to recycle properly) ... & no it is NOT a type of cantenna .. :-)
hokay thanks, i didnt know that fruit juice containers had metal in them.
