Does not have to be close to the windings you could just stick the circle of cardboard to the top and bottom just to prove it works.
Would have to work out some type of waterproofing for a long term solution
I have the same problem with packaging on one of my coils. Can't figure out why wrapping micopore tap around the coil and covering with carbon does not work as well as the cardboard. Think it might be the tiny creases that cause a none smooth coating. Need to try a couple more experiments.
Haven't tried covering the micropore before wrapping around the coil to give a more even coating
Haven't tried wrapping a single layer around the outside of the coil instead of spiraling it around
Haven't tried spacing it away from the windings
You could try the graphite spray directly to the housing.
Tried and failed with micropore tape spiraled around each winding and then covered in graphite
Tried and failed with one layer of PVC tape then space blanket then PVC
Tried and failed with two layers of PVC tape then space blanket then two layers PVC
Tried and failed with tap wire under the space blanket conductive side down
Tried and failed with tap wire above the space blanket conductive side up
Tried with the shield connected at the RX GND at the coil
Tried with the shield connected only at the box end
Tried with the coil connector shielded and none shielded
Coil covered with space blanket is worse than no shield at all
Tried some with a second TX and RX windings same results.
Gave up with space blanket
Can't find out why it does not work for me as others have had success using the space blanket.
Card worked straight out of the box. Not just a fluke as I have tried again same result. Still not quite as good as my factory coil but pretty good.
