I want to ask the community if there is a manual for build own high sensitive magnetic antennas.

I am from Austria and just working to create my self made "blue system" with KICAD (new layout, new BOM etc) because it is hard to get a kit to buy at these days......

On the german forum web site there are some docs they show the different types of antennas (E/H field) but no construction manual of the magnetic rod antenna (wire on ferrit in plastic pipe enclosure)

Maybe somebody can support

 

I wonder what kind of result you got. Photo is avaiable?
