The coating of aluminum is pretty thin. So thin you can see through it. Skin depth at 5.8 Ghz in aluminum is about 1 micron. You need 5 skin depths to effect a good reflection. But according to wikipedia, aluminized mylar has a metallic deposition of about a half micron.
So, it may not work as well as something with thicker metal. From: Jeremy Sent: Sunday, March 22, 2015 7:00 PM To: [email protected] Subject: Re: [AFMUG] Shielding 101 I'd try mylar. It's just as reflective as a mirror and probably works about the same. On Sun, Mar 22, 2015 at 4:05 PM, Jaime Solorza <[email protected]> wrote: What about mirrors?

Spray adhesive and thick restaurant foil works just as well. From: Jaime Solorza Sent: Sunday, March 22, 2015 11:45 AM To: Animal Farm Subject: [AFMUG] Shielding 101 I have doing some reading on RF shielding and Faraday cages. Lots of the articles offer examples of experiments one can try. Wavelength, dielectric, mesh wiring, etc. One mentioned using mirrors to block 95% of RF signals . Never considered that but I am going to try it. The number one low cost material cited was aluminum foil. I remember the Tranzeo radios use the duct aluminum tape to shield their units. I dobt remember them leaking RF like the Rockets. I have some Tranzeos in shop and Ubiquiti radios. After yard work I might play with these later. What are your thoughts Hobson? Jaime Solorza
