H field ferrite shielding

This has been copied over from the internal forum, station hardware firmware antenna section, 32 hours without response on a subject that if done wrong, I think, would compromise your detector. Someone within the broader followers of Blitzortung may be able to assist. Smile

""Some very interesting posts on the various ways of shielding H field ferrites. It seems that copper foil and ribbon cable are evenly matched in popularity. If I need to shield my H field ferrite antennas, I will use ribbon cable, which will be easiest to obtain. I can see that you solder one edge of your ribbon cable and then attach that earth wire to your negative connector of the antenna connectors on the pcb, for both relevant channels/antennae.

What is not so clear is how the 2 edges of the ribbon cable relate to each other. Do you have to leave a space, similar to what is done with the copper foil or do you just wrap the unsoldered edge of the ribbon cable around your conduit and just terminate in adjacent to your soldered edge (lying beside it). I assume you don't solder the other edge to the first one or do you?? The photos I have seen, do not show how the 2 edges of the ribbon cable end up around your conduit.
