To anyone reading this post about which card to get, the 1000mw or 2000mw rating Alfa advertises for the 036H and the NHR, this is because of the 9dbi antenna, not because of the card. To get the 2000mw rating, you will have to hack the CRDA file to allow you to specify the transmit power above 30. Then there's the possibility of burning out the card. If you do the googling, you will find that there is a lot more to wireless scanning than simply buying the most powerful card and the biggest antenna.
