!!! Best usb directional wifi device !!!

[nemo@arc]

Hello fellow backtrackers, i have been using backtrack for a while with my laptops stock atheros chipset wireless card and i think its time to add a little upgrade to my pen-testing. I want to add a usb directional card. The question is... which is the best??? I recalled researching this a while back and came up with
Hawking HWU8DD Hi-Gain USB Wireless-G Dish Adapter
however that was a while back. So what i want to ask you guys is.

What USB DIRECTIONAL cards have YOU USED and GAVE the BEST RESULTS?

also, any set backs if noticed on certain models?

Buy this:
Alfa AWUS036H-V5 1000mW (upgrade of 500mW AWUS036H) Long-distance USB Wireless Adapter + Antenna

and buy some of these antennas:
Antenna 10dBi Directional Panel Outdoor w/ RP-SMA connector
Antenna: 18dBi Yagi Directional 10-inch cable w/ N-female connector. WiFi / wireless (for this you need an additional pigtail)

or built your own:

(as mentioned maaany times before)

get the alfa.

Alfa AWUS036H-V5 1000mW is the one you should get. It rocks not only because of its output power , but also for its sensitivity, and its injection rate

I also got one of those Direct 24 , a 24,1 dBi solid dish antenna, that was much better than some 24dbi grid antennas i ve tested.

I just wonder,if let's say i buy this wireless adapter(Alfa AWUS036H-V5 1000mW (upgrade of 500mW AWUS036H) Long-distance USB Wireless Adapter + Antenna),why do i still have to buy additional antenna like erhardm mention??(Antenna 10dBi Directional Panel Outdoor w/ RP-SMA connector
Antenna: 18dBi Yagi Directional 10-inch cable w/ N-female connector. WiFi / wireless (for this you need an additional pigtail)??

Anyway,I'm a complete novice,so i just wanna consult any expert,why does the antenna is needed??But why my current ordinary usb adapter doesnt have any antenna but I still get to connect to the internet,of course i'm not using backtrack on it??my current usb adapter is shiro wa54-u.Any idea??

I want to add a usb directional card.

The adapter comes with an omni antenna. If you don't need directional then go only with the ALFA

Being a novice you will need to check this thread and try harder(tm) at Google's search engine:

the idea is, a standard wireless card thats not directional radiates a signal in a circular radius all around the wireless card, using an x amount of power. but if we focus our signal NOT all around us, but to a particular direction. we can still use the same x amount of power, but now we get an increased distance of communication because all the signal power is being focused to a particular point.

Thanks for guiding me,anyway,I just wanna know is there any guide or thread that teaches everyting about a wireless usb adapter and all those stuff regarding wireless(omni-directional,wave i keep heard and others).I wanted to learn about it so that i can choose a decent wireless adapter for myself,now i'm lacking of knowledge on it,for example I've no idea about the 1000mW in the name of this wireless adapter "Alfa AWUS036H-V5 1000mW (upgrade of 500mW AWUS036H) "
