What is the fourth antenna lead that connects to the wi-fi card?
Hi. There are four antenna leads that connect to the wi-fi / airport card in my Macbook Pro. While three of them are part of the Airport antenna assembly and can be easily replaced, the fourth, longest lead seems to originate from a mooring at the uppermost left of the Mac's bottom casing itself. I've damaged the delicate connector and need to replace it, but I don't know what the lead is called, what it does, or how to source a new one and effect the repair. Can anyone help?
Is this a good question?
