Hi Ian & Charles, When we put in our chamber (Boston area, MA), we used dielectric breaks to all connections and mounting, isolated the power to the chamber and test equipment and then used a dedicated ground from ground rods. We were required to drive 3 rods, 6 ft down, we ended up driving a 4th because # 3 only went down 4 ft. Regards, Charlie Martin

Hello Ian, A single ground rod should suffice – but it all depended on building codes!

We are due to move our EMC screened room within the next year to a new site. It is planned to be placed in a much larger building of steel and concrete construction. We have planned it to be placed close to an outside wall so we can pick up an outside earth which will be bonded in to the mass of the earth for safety reasons Could l hear your ideas on the best solution for earthing the screened room as l feel the present arrangement may be far from ideal. For example is it better to use a number of rod earth electrodes or some sort of steel mesh arrangement buried in the earth for a good RF performance. Thanks for your help.
