I recently obtained a refurbished Powerbook G4. It's one of the newer
models (M8980LL/A) with specs:
15" screen
1GHz G4
256MB DDR2700 (333)
60GB HDD
Built-in Bluetooth
Firewire 400 and 800
Airport Extreme Ready

My problem lies in that the Airport Extreme Antenna Cable is buggered.
The plug that is supposed to attach to the Airport Extreme card is
missing. Looks like it was ripped off or some such thing. The
company is looking at it now to decide to repair the problem or
replace the whole unit (with a different refurb).

I am wondering if anyone has ever had a need to replace this cable
(for any reason) and if so, what was involved?
How is the cable attached on the other end (I didn't take off the back
panel)?
Soldered to the motherboard and the antennae attach there as well?
Direct cable from the antennae to the airport card, so I'd need to
replace all of that? Or what?

Like I said, they are supposed to remedy it, but I was just wondering
what the chances are of repair or a different replacement unit.
