Well, I plan on only really using it in my home. However, I am the type of person that prefers to go all out on this sort of thing just in case my intentions or needs change. What would your suggestion be if I were planning on using this as an audit tool. A situation where I would be using it for pen testing along with a couple of antennas and maybe an amplifier. I mostly want to try to make this purchase once. Also, any suggestions for a pair of cards to be used together? For man in the middle attacks and such. Thanks for the quick response too.
