And the import and relevance of this article is... what?

...theft.

Or improving the performance of your own wireless network. The range of some of the internal antennas is not particularly great. The fact that this antenna is directional will not only improve performance, but make the theft of your own signal less likely.

The number of persons who use these antennas for legitimate purposes is so small as to not be worth mentioning.

You can buy a far more functional and unobtrusive +14 dBi directional antenna for $100.
