Quoted regularly in 'RadCom' by Pat Hawker back in the 70's and 80's KISS (Keep IT Simple Stupid....or Keep It Simple Steve!)
Came across this which gives a really simple way of extending the range of a Wi-Fi link. Wireless Network antennas are usually omni-directional and have a small 'rubber ducky' type helical aerial. Making it directional, hence increasing the gain can be useful. I know at school we have RF deadspots in rooms and i'm sure this would be useful.
The 'Windsurfer' is simply a piece of card covered in foil which acts as a reflector for the 'rubber duck'.
