I have a dell d600 latitude laptop that I am trying to figure out how to install a external antenna to. I was reading another post on here where someone said the wireless card antenna terminals were marked MAIN and AUX.,which is true,my question is then I should be able to follow the Aux. wire to the opposite end and somehow connect an external antenna,am I thinking right?? I am not sure where the internal antenna is.Its not behind the screen!
