It seems to me that I have seen stuff like this, but it was never
referred to in your terms. It is an old idea, back into vacuum tubes,
as mentioned.
The devil has always been in the details, and whether such stuff could
be manufactured reliably in quantity, and whether it would be rugged
enough to withstand real life, and whether it would have enough range
away from the extremes to create practical circuits for other than
conceptual demonstration. I'd always suspected that was never
overcome, since you can't buy them off the shelf at Radio Shack.
I don't own one but DX engineering does something off in that
direction with their active listening antennas. That's about as far
as I've seen anyone get.

Thanks Guy, it looks I will have another idea to experiment with.
