Paint yourself a Faraday cage

For the Amateur Radio operator who has everything, now comes the possibility of an expensive fix for electromagnetic leakage from or into the shack.

A company in the USA is selling an additive to normal paint that effectively turns the paint into an RF shield.

It seems that the aluminium and copper fibres bond and "the hard fibered film will reflect and refract radio waves, preventing wave transmissions by as much as 90%. Dissipating radio waves in there (sic) path."

Oh, and it is marketed for those people wanting to prevent unauthorised use of WIFI connections, so it is intended for the gigahertz bands.

At only A$47 to treat a 4 litre can of paint that you have to buy anyway, I'd recommend you have a very clear idea about what part of your radio environment needs to be treated.

We report; you decide.
