I've always assumed that the performance of ferrite-rod antennas in
transmitting applications was limited by core saturation. Wonder if
there's anything to this "invention"?

not much info there, but i've read articles about russian experiments on
small antennae and something about a capacitive antenna.

somewhere in the jumble, i came across a theory/claim supposedly
originated by Nikolai Tesla. the theory being that applying a large
voltage - low freq. ac, dc... i don't remember - to a short antenna
would set up an electrically large antenna by virtue of the electric
field.

say you applied 1000V to a 1m whip. that's 1000V/m. or it's 1V/m over a
length of 1000m effective antenna length. that's the theory... key word
"theory".


You're misusing the word "theory." You mean hypothesis. I know, I know,
I'm nitpicking. But I once was chewed out by a physicist at MIT for
misusing the word when I was temping there. Ouch.

PS:

theory - a proven fact which explains an aspect of nature; i.e., the
Theory of Relativity.

hypotheses - A tentative explanation that accounts for a set of facts
and must be proven by further experimentation.

yup, it may be nitpicking, but yer right. that was explained on day 1 of
7th grade science.
