My friend's iBook G4 slowly lost connection range to their base
station, to the point now where you have to be standing right beside
it.

I did some poking about on the 'net, and it seems this is a common
problem. The antenna runs through a hinge that wears on it and causes
this problem.

Does anyone have a guide or any advice on replacing the antenna?

It's probably not the antenna, but the connection. You may be able to
open the iBook and reattach the loose cable from the AirPort card to
the antenna.
If not, add an external antenna from a vendor like www.quickertek.com.
They may have additional ideas on how to diagnose your problem as well.

If it is the antenna you should see the strength indicator go up for
certain positions of the screen. When ours failed it connected with the
screen closed to 45°. If you have that effect then yes, you need a new
antenna.

But you say it "slowly lost connection"...?? Can you get another comp.
to see if the signal is there? Power-cycle your router? Go somewhere
where there is a known good signal? Can you borrow another Airport card
to see if that's where the trouble is?

iBooks are known for good reception, the external antenna should not be
necessary.

If you do need a new antenna, you'll have to buy an assembly first (the
micro-coax cable cannot be repaired where broken). Then you more-or-less
completely disassemble the iBook & screen, get out the old antenna and
put the new one in. Took me >4 hours to do this for our iBook, but then,
I have experience with things like that. If you want to do this, get
your manuals here: http://home.earthlink.net/~gamba2/index.html. Do not,
repeat: NOT, try to do this without a manual, you'll end up with a pile
of useless parts.

Get your antenna assy. from Powerbook Guy or from pbparts.com. Was $100
about 1.5 years ago. Apple I think takes $350 flat rate for any repair.
