Yeh but if I understood Eduardo the OP's question it was all about improve the reception of signal not any improve sound thing, OP seems to have a bit marginal wifi reception where he intend to place the Touch ? Hence my non DIY suggestions as a way the to the objective .

Thanks for all your feedback, guys.

OK if you are still interested in an external antenna.....
First I'm really not convinced that a short coax pigtail can possibly any worse than having the actual antenna exposed inside the touch case.....I just do not buy that at all.
I would disable the internal antenna and route its connectivity to a surface mount UFL socket like I showed in an earlier post. You can see the trace from the wifi chip running left to right in the picture. This trace is connected to the pads of C162 and C163. In the shown standard configuration, there is only a cap in position C162 coupling the trace to the internal antenna. By moving the cap C162 into position C163 you isolate the original antenna and couple the new UFL socket. You can then use a short UFL to SMA cable which the SMA mounted on the back case of the touch.

Another way?
Forgive me if I'm missing something here, but if the desired end result is a stronger (wireless) signal for the Touch for "improved fidelity" then how about boosting the existing signal from the router with a wireless bridge?
I have a couple of extra Buffalo Airstations configured as bridges in my network for exactly that reason.
If, however, the OP really wants to mess with the guts of a Touch then I can see that what I've suggested is really stoopid ...
Thank you and good night ...

Other than actually directly addressing the thread title, what I personally am looking to achieve is to remove the antenna from the proximity of the touch and maintain the wireless function.
As an example, if I bring my mobile phone anywhere near my MC phono stage it picks up the interference. In the same way it conceivable that a similar effect would exist with the antenna inside the touch. Moving it away may or may not make an audible difference but for me, this is now just about trying it to see how easy the external antenna function can be implemented. Clearly the pcb was designed to cater for an external antenna as the pads for the socket exist. Should it be of any use to anyone else along the way then all the better ;D
