I am installing some antennas on a building, and I need to color the antennas to match, without cutting the signal. Can anyone recommend a brand/category of paint, dye etc. that is relatively Wifi-transparent, and comes in a decent selection of colors? In this case I’m looking for a brick-red, but if I found a product that worked, I would be using other colors on other projects.
(One of the costs of working in an area with a lot of historical buildings…)
I have seen regular spray used and not be a problem. As long as it isn’t metallic it should be fine.
I was thinking more in terms of pigments being based on Titanium & other metals. This link suggests that general-purpose spray paints like Krylon & Rustoleum are fine, but I was hoping to find more authoritative results to go on, like a manufacturer’s data sheet. The most useful information that I got was that TiO2 and other metal oxides tend not to be RF-opaque like their elemental metals would be.
It looks like I’ll be buying a couple brands of paint tomorrow and doing the microwave test, and/or an A/B test between painted and plain sheets of paper using 2.4GHz and 5GHz radios.
On that That Link I like the advice
Ok… what is the microwave oven test prove???
Spray some cardboard and if it has metal in it then spark test will show it…
Yea, If Your oven starts on fire, Don’t use it.>
> . No, on the serious side, if it turns black or brown, there is probably metal in it.>
