Aluminum and copper are not real apart on the galvanic table. Stainless
steel and aluminum are a much worse combination. I would use conductive
grease such as Penetrox between the Array Solutions device and your
plate and simply bolt them together. I have copper and aluminum
connected together in my ground system and I have not seen any issues.

Hello

I will be doing coaxial grounding on shack entrance.

Need to install ArraySolutions AS-303 surte arrestors on a copper
surface.

AS-303 have aliminium case. So, i will install them with two screws
directly on the copper plate or is best to apply something to the two
surfaces that will be in contact?

thanks!
