Turn your standard WIFI antenna into one just like the $30 range extender antennas for about 5 cents! Follow these easy steps, and then check out the video if you need extra clarification. Digg if you like my very first Instructable.
Step 1: Remove the Top of Your Stock WIFI Antenna.
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 sevenh loop. just unscrew the drywall screw to remove it from the wire.
Step 4: Measure Off 3/4" From the End of the Coil and Cut.
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 cards and routers. See my video to see the results, and Digg this if you like my very first Instructable! 8D
