Sure, its still possible that I could still help.
What more do you need?
You have the general idea of what you want to build. You need to gather the materials, and build it.
The only thing I see that may hold you up is you do not know for sure how to connect your project to your wi-fi card.
It does look like those black, and white wires are for the antenna connection.
See pixs 4,5,6 at : Part 3: Installing an atheros wlan card
They slide/snap on to a antenna connection.
What do yours connect to? Can you show more pixs? Need more pixs!
It would also help if you filled out your System Specs
, especially the make/model/serial number of that Atheros adapter.
