funny thing is their data gathering can probably see multiple keys pressed at once (as fist repeatedly contacts keyboards) - I wonder if they can detect loss of monitor (as it flies through the window).

use this website for the math: http://www.changpuak.ch/electronics/yagi_uda_antenna.php then simply use the wire you have to build the yagi antenna. highly directional with a large forward lobe this should do the trick. I see the boom length is small for 800/1900Mhz (I think that's 4G freqs). Naturally purchasing one will save the time/effort to solder/clamp the elements to the boom and the coax to the antenna/connector but there's nothing more satisfying that a bit of home-brew kit. HTH
