As you can see this is a wifi router antenna I've modded.so lets get started shall we!!
First if you have an extra/old wifi router antenna I would recommended u use it for this project.mine I've scavenged from an old router I used to use till I decided to upgrade.
First cut the silicone or plastic of the wifi router antenna at the base as u can see I did,I would recommend useing a small wood saw!!!
Take the router plastic of here u will see the antenna. As u can see I've already modded mine!!
Strip the wire a centimeter from the base and solder some red copper wire on it ur gonna want to add about 11inches of the wire.
Find some old pens and take the outsides of them and make an outside chamber for the wire to fit in and hot glue the pen shafts. Together and put it over the wire and hot glue at the base.add some spray paint to give it a professional look!!!
Congrats!!!! now screw it on ur wifi router and experience ur boosted wifi!!!
