Summary[edit]
DescriptionWi-Fi Cantenna.jpg |
Another cantenna project. A friend of mine is the director of a local non-profit organization in Ashtabula County, and they had permission to share Wi-Fi from a nearby church but couldn't get a signal. I built a cantenna which solved the problem. This one is mine which I built for fun, but they'll be borrowing it for a few weeks while they have an intern working for them. Building these has been a lot of fun and it's nice to see them used for a good cause. This one is mounted to a $2 camera tripod I picked up at Micro Center. An ALFA Network AWUS036EH 802.11b/g USB adapter (which has an SMA connector) drives the whole thing. I haven't had a chance to test it to any great extent, but Kismac does seem to pick up on more activity with this adapter than with my customized Linksys WUSB11 2.5. The ALFA adapter uses an RTL8187 chipset which is supported in Kismac 0.21a revision 319. I used this website as my guide for building the cantenna: www.turnpoint.net/wireless/cantennahowto.html I've uploaded my cantenna photos at a larger size than I normally do for the benefit of anyone who is thinking of building one. It's pretty easy, but you'll need a soldering iron and drill, and if you want to clean up the edges of the can a Dremel is handy too. Have fun if you try this! |
