Review on 🔌 Inch Yds Copper Foil Tape: High-Quality Conductive Adhesive for Various Applications by Gary Duncan

This is the cheapest copper foil tape with conductive adhesive that I could find. It seems ideal for Faraday cases made from metal dustbins and for sealing foil wrapped Faraday secondary cases used in a metal container to achieve >-50dB shielding efficiency. At this level, most of your electronics can be salvaged in the event of an EMP. You'll need lots of tape when opening the crate, using items in the crate, and repacking items into your Faraday Crates. As stated in the tape specs, it's only 1 mil thick, but that's good enough for this application. I measured the resistance of the glue to copper and it's in the sub ohm range. There is a really great book that describes Faraday packets and how to make your own. I have nothing to do with this publication. I just bought it and applied its recommendations. The title is "Disaster Preparedness for EMP Attacks and Solar Storms”. It was written by Arthur T. Bradley, who has a PhD in electrical engineering and works for NASA. Read the book, build a Faraday box (you'll need a place for the electronics) and use tape like this to seal the box. Your gear will be protected. I used metal trash cans. They're strong and cheap, but they don't seal perfectly. Using conductive tape like this to seal the trash can and secondary enclosures will protect you from 100kHz to 1GHz with over -50dB of attenuation at all frequencies in that range. Last note. Most information on the internet is useless. There is no point in throwing FM radio in the trash. You need laboratory equipment and methods to make useful measurements.
