I just made a poor quality one of these with plain old paper and aluminium foil. My iwlist scan results: Frequency:2.437 GHz (Channel 6) Before: Quality=40/70 Signal level=-70 dBm After: Quality=47/70 Signal level=-63 dBm Not very exciting, but not bad. Lots of access points in my block make connectivity a real problem, so I'll take whatever I can get. My roughly-cut parabolic reflector isn't super-parabolic, make of that what you will: maybe a better shape would be markedly better, maybe it means yours doesn't have to be perfect either shrug My tips if you want to try yourself: tape the tabs in place but try not to put creases into the foil when you do. If it's not already clear, only put foil on the back reflector (not the curved support)
