Learn how to make a dirt simple (basically free) wifi antenna booster using tin foil.  Yes, it sounds crazy, but it actually works and significantly increases your wifi signal in the dead zones of your house. The video above is pretty lengthy, but does a good job walking you through a few optimal designs.

You can make this wi-fi parabolic antenna for your router without breaking a sweat.

• Manila file folders
• EZ-12 Templates for the antenna from Freeantennas.com
• Adhesive
• Aluminum foil

The parabolic antenna is nothing but a focusing device cut out from the stiff manila folder and backed by a layer of aluminum foil on the back for the reflective surface. The exact cutting pattern is aided by the EZ-12 template.

As the video shows, the construction is as easy as an elementary school project. The effect is pretty impressive for such a simple device. You can expect a signal boost from 9 to 12dB. The signal gain depends on the size of the antenna and the number (1 or 2) in use with your wireless router.
