Antennas concentrate EMP? oh well, have it your way.
Nearby Massive metallic structures may increase the fieldstrength of EMP but will not 'suck' the EMP away from you or away from other nearby things.
The following (from the link) is True:
"The only two requirements for protection with a Faraday box are:
(1) the
equipment inside the box does NOT touch the metal container (plastic, wadded paper, or cardboard can all be used to insulate it from the metal) and
(2) the metal shield is continuous without any gaps between pieces or extra-large holes in it.
Grounding a Faraday box is NOT necessary and in some cases actually may be less than ideal."
A nuc explosion is not required for EMP to be produced.
A conventional device can be easily constructed to do the job.
This is all fine and dandy but does it really matter?
Ponder it all.
