Simple electromagnetic radiation, the same as from your TX.
Remember spark transmitters? I don't either but I've heard of them. :-)
In fact, this phenomenon is how radio waves were discovered in the first
place. See http://en.wikipedia.org/wiki/Heinrich_Hertz
for a discussion of the subject. Oddly enough, the phenomenon was predicted
by Maxwell and Faraday before it was actually observed. It must have seemed
like black magic at the time.
