How is the loop wire put inside the copper tubing? What gauge wire? How many turns?
Details would be appreciated!

Yeah, the 'specs' and stuff are rough figures, and maybe a little screwy, and poor examples, but can't beat the performance.
and
The 'CSS Thingie' ferrite: beats heck out of any of my other ferrite builds, second only to the Wheelie for response and resonance...

Whatever theories and measurements, both prove themselves in operation.
...and, if you stick a thingie inside a "Pesky Shield", might just eliminate a strange interferer or two, plus a bit of signal enhancement.
