 It is highly directional and a few degrees left or right of the target will make a significant difference. It is highly directional and a few degrees left or right of the target will make a significant difference.
  
-The measured gain is around 13dB which is 20 times the strength of the USB stick without the can. This is amazing gain for the simplicity and “cheepness” of the system!+The measured gain is around 13dB which is 20 times the strength of the USB stick without the can.

 This is what I measured using professional measuring equipment from work, I’m astonished at the results myself! ​ This is what I measured using professional measuring equipment from work, I’m astonished at the results myself! ​
 Due to the internal construction of other USB wifi devices the gain may vary. Due to the internal construction of other USB wifi devices the gain may vary.

 The size of the can is important when designing a proper antenna system, however, the parameters of this can are in fact not the correct ones for the frequency of wifi but as you will see, work very well and are a compromise. The size of the can is important when designing a proper antenna system, however, the parameters of this can are in fact not the correct ones for the frequency of wifi but as you will see, work very well and are a compromise.
