Anything conductive. Aluminum foil works, but you can also get thicker pieces of foil that are easier to work with on Canal street. I also bought some copper tape with conductive adhesive for grounding purposes online for about $15 once. As long as the width of the metal is not near a quarter wavelength in any dimention it should act as a simple reflector. At the harmonic frequencies it will absorb an reradiate the signal. Make the strip 3.5 inches wide and don't worry about...
BTW at 0.1 Watts I would bet all my money there is no danger at having the radio sit in/on your privates. Are you amplifying the signal? WiFi isn't like those Cell Phones that operate at 2 Watts that people stick next to their heads or in their pants pockets, this is 0.001 to 0.1 Watts we're talking about. And like all EM (radio) radiation the biggest threat is often unwanted concentrated heat. Our watery bodies are pretty darned good heat conductors. If you're on a bike outside the sun should be your radiation worry, it sends out all kinds of harmful rays that you want to minimize your exposure to. Your eyes and skin can be exposed to lethal doses, especially on cloudy days or in winter when many forget to protect themselves from UV (Which goes straight through those clouds. Look for the bluish glow in UV sensive plastics used to seel drink bottles on a cloudy day sometime.) -- Daniel << When truth is outlawed; only outlaws will tell the truth. >> - RLiegh On Sun, 19 Oct 2003, Yury Gitman wrote: ]Anyone have experience with the materials that are ]used to shield, deflect, or dampen the 2.4ghz signal? ]Or, have a clue what the materials are and where to ]buy them?
