I am about to fit a Firdell Blipper radar reflector to my mast. In order to prevent corrosion between the stainless steel reflector bracket & alloy mast I was going to use stainless steel self tappers together with insulating washers between the bracket & mast. But even using this method, I believe that the self tappers will still cause corrosion as they are in contact with the mast. Can anyone advise me on how this simple job should be done properly to eliminate the possibility of corrosion occuring?
