[maemo-users] How is the N800 antenna implemented?

[From: david.hagood at gmail.com]

Does anybody know how the antenna in the N800 headphones is implemented?
Are they using the ground conductor as the antenna, are they using the two
headphone lines as a dipole antenna, or what?

There are 2 reasons I ask: first, I'd like to be able to do a calibrated
sensitivity check on the FM receiver, which means I need a proper RF
interface to inject the signal from my sig-gen on. Secondly, I work in
what can best be described as RF hell (as you might deduce by the fact
that I have ready access to a calibrated RF sig-gen), and I'd like to be
able to couple my external antenna drop into the N800.
