[NLRS] Need EMI Conductive Tape

[Dr. Gerald N. Johnson]

Would that capacitance be enough at 2 MHz compared to isolating 2 GHz?

Even though the adhesive is not conductive, the width of the tape on either side of the seam serves as a nice low impedance capacitor, and the overall shielding effectiveness is nearly the same as if you were using copper foil tape with a conductive adhesive.  ( the kind with the little copper slivers in the glue)
