Default Looking For Ideas & Recommendations

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.

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.
