Another cheap device that uses these frequencies are baby monitors. Devices on these frequencies are referred to as "part 15" devices, for the FCC rule regarding unlicensed transmissions. Only a small block is allocated to these frequencies, so they all have to share. There are a lot of part 15 devices around that could be used for this purpose.

I don't see any need to press all the keys in the keypad down, dialing numbers doesn't change the strength of the signal.
One other thing I would do is use either 4.92 (full wave) inches of bare wire or 3.69 inches (3/4 wave) and I think I would prefer to fix the ends pointing in exact opposite direction like tape to the middle of a ruler and stretch each wire toward each end (di-pole style).
Then again this assumes the "jammer's" proximity to the wifi antenna to be extremely close, I would think.
Cool link anyways. Damn I sound like a geeky old ham radio guy.
