Re: Antennae?
A convenient antenna may be hard but an emergency antenna is easy. The difference between any two metal areas can be used. For example, it could be the difference between the case and the NFC loop shield. For that you'd hold the metal case with bare fingers and place the NFC loop over another body of metal. It's crude but you could get your broadcast on where to find emergency supplies.
Alternately, the Qi charge loops would make for a pretty good AM radio antenna.
