[Lowfer] Copper pipe loop question

[Gedas V]

How about covering a plastic loop with the copper foil we used for EMI &
TEMPEST work? A long time ago you could get a roll of 3M copper tape 2" or
3" wide and 20' long for $30 or so. Not sure what the prices are now. But
even a 3M clone brand will work as long as it's copper. Heck, now that I
think of it you can get a huge roll of Aluminum tape/foil used for HVAC for
less than $10.
