I read the patent application meantime. But I must say there is not much
content in it. Especially nothing how to calculate dimensions, materials
or
taken measurements.
My understanding is that it is a helix antenna supported with a ferrite
powder rod in the axis. And it is electrical much longer than the
wavelength
used. Adaption to the "ether" field Z(0) with up to 4 stages of different
winding/mu(r) value materials. A magnetical antenna very similar to the
electrical Yagi antenna. "The antenna works up to 500MHz", he says.
"Greater
frequency requires lower mu(r)."

Thanks, that at least makes some sense of the sales story.

Sorry, maybe it won't work at all. I'm not an antenna expert. Maybe the
author of the patent will directly respond here sometime?
What do you think?

I'm not an expert either, I just got triggered by the nonsensical "will work
even when cast in metal" thing. I've constructed enough RF electronics to
know when even a thin layer of copper (or aluminium) will shield EMC almost
perfectly (closed box aka Faraday cage).

I checked the Norwegian patent office but they cannot afford a decent free
publication site like the US has. Do you have a link to the patent or would
you care to send a copy to (a temporary address)?

Oh yeah.... do try the experiment and be amazed...
