Just because you're German doesn't mean you can say 'tight glands' without a snicker. 'Highly conductive gaskets' is perhaps less likely to amuse the more adolescent among us. Faustine, look up Faraday cages, TEMPEST, and search the archives. As if you didn't know. Succinctly, the electron gas in metals shields you from the electromagnetic antics of distant, radiating electrons, by shorting the ripples in the aether they make -and this shielding makes it harder to listen to your emissions, too. The problem is that cables and ventilation vents are antennae, for sending and receiving both. Testing is key. If you don't measure, you don't know.
