H field ferrite shielding
#5
Didn't one member take a length of copper pipe, slit it from end to end, open the diameter up a bit creating a gap, and slide the PVC pipe with ferrite in it, into the copper tube?

I think the report was finding a PVC pipe to hold the antenna that was the right diameter so the copper tube when stretch open into a "C" was leaving the right gap.

I ended up using copper foil that I got from a supply place for musicians, since it seems some of them put it inside the guitar sounding board to shield electronics mounted inside. A bit pricy but worked well and was easy to solder the ground to.

Jeff,
How long did you start out with for the Efield antenna and what did you decide to trim or extend it to?
