wrote: 1. Is there wire with camoflage insulation? (just kidding!) No, but you can easily dye vinyl or PVC insulation in whatever colors you find useful. I once built a wire striping machine, that produced a red and white "candy cane" pattern. Please don't ask why. I plan on using wire with beige or tan colored insulation. I think sky blue or grey would provide the wrong contract. I think you mean contrast, not contract. There are vendors that sell "stealth" antenna wire. It has a copper plated steel core wire and clear insulation. Or, just the copperweld wire, and no insulation. http://www.universal-radio.com/CAtalog/cable/polystealth.html http://fushicopperweld.com/en/bimetallics.html Any suggestions on the best way through the hole to prevent any problems? If you drill through the wall, drill at a slight angle so that water will drain out of the wall, rather than into the wall. Use PVC electrical conduit parts for the feedthrough. 4. Is there a way to tell if the glass in my windows has some property that greatly attenuates signals? Yes. Read the label on the window. If it says Low-E glass, it's probably coated with Titanium Nitride to reflect infrared. TiN is about 40 ohms per square, which is highly lossy at RF. You can test it with a cell phone. Compare the signal strength on both sides of the window. If there's a drastic drop in level through the window, you have Low-E glass. Note that all new construction and remodels in California have required Low-E glass for the last 10 years or so. http://802.11junk.com/jeffl/crud/Low-E-titanium-nitide-glass.pdf -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
