5N30.20 Skin Depth

[Setup Time: 5 Min.] [Current Condition: OK]

Info

Wrap up a hand-held radio in aluminized mylar, and hold the mylar tight across the speaker so the sound gets out. If the radio is playing AM, the same levels are heard as without the mylar. If it is playing FM, the aluminum blocks the signal and only static is heard.

Should be ok, but i need to see if I have enough mylar for the new radio.
