Turn your standard WiFi antenna into a $20 range extender antenna for about 5 cents! Check out the video and follow these steps.
1Step 1:
Remove the top of your stock WIFI antenna. A small flat jeweler's screwdriver works great!
2Step 2:
We're going to match the Range Extender layout form as you see here. You'll need: small gauge solid copper wire, insulated or non-insulated, and a wood screw/drywall screw, measuring tape or ruler, and a soldering iron.
3Step 3:
Measure off 2 3/4" of your wire and make a small bend. Then, starting with the bend, use the grooves of the drywall screw as a template and make 7 COMPLETE loops, then bend the wire flush to the screw after the seventh loop. jus�
4Step 4:
Measure off 3/4" from the end of the coil and cut. Then strip off 1/8" of the insulation or sand off 1/8" of the coating on non-insulated wire (depending on what you're using).
5Step 5:
Cut down your stock antenna to 1/4" And then strip off 1/8" of the insulation.
6Step 6:
Solder the new antenna onto your cut down and stripped stock antenna. Overlap all the bare wire from the stock antenna base and the new antenna.
7Step 7:
Use a large diameter drinking straw and slide it over the new antenna. McD's has them... they're slightly larger diameter than a regular drinking straw. I think they're for shakes, etc.
8Step 8:
The straw fits perfectly and snugly on stock WIFI antenna bases. Amazingly, you don't even have to glue them. It's a match made in heaven! Use a black permanent marker or paint for a pro look...
9Step 9:
All Done! Looks pretty good! You get a more omni-directional output (less fiddling with exact antenna placement) and approx. 5 dB gain. It works REALLY well on both your wireless card or router�
