A new swing on an old idea for improving your WIFI signal!
I call this WIFI booster ad on the POPtenna because you make it from a plastic pop bottle.
First get a clean plastic 2 liter pop bottle.
Strip off the label if there is one and wipe down with a cleaner that does no leave a residue.
Using a large sharpy pen, mark a ring around the bottom and a window that takes up just half of the diameter of the bottle as shown.
Cut out the window first so the bottle will have stiffness to help with the cutting and then cut off the bottom of the bottle.
After doing all the cutting, you must clean out the bottle's inside with windex or an equivelent cleaner.
The as you see by the photo.... get out your tin foil and glue stick and get ready for the next step of lining the inside face of the bottle with tin foil and making it as smooth as possible.
As you can see by the photo, it is only the back of the inside that gets the tinfoil. This is to make a vertical dish to focus the signal beam back into your vertical omnidirectional antenna.
