What Richo said about having the copper tubing too close to the ferrite makes sense. My ribbon cable arrived today and I am in the middle of earthing one side and setting up the new casings. I actually had some more tubing left over for the casing of the efield antenna and I am going to use that for my ferrites. It has an internal id of about 35mm, which will match Richo's optimum set up for H shielding.
The e field started out with a meter but have trimmed it back to 35cm. I found with the metre length when storms were close, I wasn't getting as many detections (overloading the signals I think) that I think I should have. Will now have to wait for some passing storms to see if it made a difference.
