You'll get even better reception if you shape the wire in a fractal pattern, like this: http://www.instructables.com/image/FDXQQVBFP8NM7YF/Create-fr...

Nathan Cohen made this discovery after listening to a Mandelbrot talk on fractals: http://en.wikipedia.org/wiki/Fractal_antenna#Fractal_element...

"Nathan Cohen made this discovery..."

He's the reason you don't have a stubby antenna sticking out of your cell phone anymore. Really cool story.

I watched a Nova on fractals not too long ago, it covered this bit exactly. Definitely a cool story :) I don't 100% remember the title, but I think this was it: http://www.pbs.org/wgbh/nova/physics/hunting-hidden-dimensio...

"Nathan Cohen made this discovery..."

Surprisingly he does not have a wikipedia article. You'd think someone who made such an important discovery would have a rather long one.

I can't be the only person to notice that not every angle on the instructables example can be 60 degrees.
