DIY - How to Make a Conetenna WiFi Antenna that goes 18Mb at 300 yards!

Well, here’s a wifi antenna you can make that can do 18MB at 300 yards.

Now here’s a way to get some free wifi from your neighborhood, that is if you live in a metropolitan area AND you have a window to high-rise apartments.

This antenna performs better than the dish antenna I had built, so I’m happy with it. And maybe the world is a better place now that I’m not weilding a truly Buck Rodgers death-ray of an antenna!

From 50 yards, I’m almost getting a full strength signal. And at the shooting range I’m getting an 18 Mb connection from 300 yards. But the side-lobes are huge! The signal strength meter starts to drop at around 30 degrees to either side of the antenna. Good to find a signal quickly, but I want more focus.

Now that this is what I built, I’m thinking about building a 5-gallon bucket antenna. If I can put the wave-guide inside of the cone, make the cone bigger, who knows?
