Fixing the Transponder with Duct Tape and Aluminum Foil

There are some special versions of copper tape that are specifically labeled
"conductive adhesive". So far as I know, they are only made by 3M and are
gawdawful expensive. And, I got bit in the butt once by assuming (terrible
word) that the adhesive parts would remain adhesive over time. The "conductive
adhesive" only gets its conductivity through copper dust mixed in with the
stickum.

If that stickum comes loose over time or temperature, you've got one hell of a
good slot radiator on your hands, especially at a gigahertz or two.

shared these priceless pearls of wisdom:


- One bit of curiosity I have, about the copper tape: How does the "sticky
- side" affect electrical connection? Is the adhesive conductive?
-
-IIRC it's not conductive, but it's not much of a dielectric either so I
-imagine there's some coupling across the layers. The tape acts more as a
-reflector than a conductive shield.
