The link that I posted only has the antenna, not the cable, so you need to go find a cable as well. If you have line of sight, then try putting the access point in a window that can see your destination point and try it out without an antenna first. I'm using my access point in a 2nd story window that doesn't have line of sight across the diagonal of a busy street and I can still get a signal. This saves me from having to go buy an antenna. Try it out first in the line of sight, I dont know if you tried that yet.
