How to Build a Homemade Antenna Booster
A wireless (W-Fi) antenna is designed to focus radio waves hitting it for transmission to a Wi-Fi capable device -- for example, a laptop. You can build a homemade antenna booster by employing the principles of a parabolic reflector. The parabolic reflector will intensify the reception of the radio waves hitting the antenna, resulting in a stronger, more stable signal than otherwise would be possible. A few household supplies are all that you will need.
Things You'll Need
- Printing paper
- Manila folder
- Cellophane tape
- White glue
- Aluminum foil
- Utility knife
- Wi-Fi antenna
Download and print out a parabolic reflector template from a website such as Binary Wolf (see Resources).
Place a manila folder on a work surface. Place the template-printed sheet of paper on the folder. Tape the sides of the two together with strips of cellophane tape.
Turn the two over. Apply white glue to the back of the manila folder. Tear off strips of aluminum foil and place them on the folder until the surface is completely covered.
Press down on the foil to secure it to the glue. Let the glue set for an hour before proceeding. Cut off excess foil from the sides, top and bottom of the folder with scissors. Turn the folder over.
Cut through the slots printed on the rectangular shape on the printed paper with the blade of a utility knife; be sure to cut through the folder and the foil beneath the printed paper as well.
Cut through the outline of the rectangular shape with the blade of the utility knife. Cut through the outline of the circular shape, including the extruding slots, with the blade of the utility knife. Remove the cellophane tape and discard the printing paper.
Turn the circular shape over. Fold the top of the circular shape toward the bottom. Smooth the crease down with your fingers. Turn the rectangular shape over.
Insert the tabs on the left side of the circular shape into the tabs on the left side of the rectangle shape. Insert the tabs on the right side of the circular shape into the tabs on the right side of the rectangular shape. Tape the tabs to the rectangular shape's back with strips of cellophane tape. Push the left and right sides of the rectangular shape inward slight to bow the sides.
Punch a hole through the top of the circular shape at the center point between its left and right sides, using the utility knife.
Push the Wi-Fi antenna's tip through the hole in the circular shape from the bottom. Keep pushing the antenna until the tip exits the top of the hole.
