Lightining, direct hit to a TV antenna.  Antenna and #6 CU ground 
lead were reduced to little BBs or otherwise vaporized.

The affected systems were one floor down.  Not less than two portable
(battery only) radios had the RF stages fried.

The term EMP is ElectroMagnetic Pulse refers to any large 
magnetic pulse.  It is not exclusive to a nuke going off though that 
can generate a whale of a big one.  Though dumping a sufficiently 
large (say 100KW/S) stored charge into a coil can really mess 
up local equipment.

Years of working around commercial towers I've seen what those 
big sparks from the sky can do.  Its impressive.
