There is a new Bonding method for the WildBlue Satellite Dish. Doing so I have to install a dual aluminum ground lug to a steel mount bracket for a wall or roof mount, and install a dual aluminum ground lug to a galvanized pole for a pole mount. I am worried about a chemical reaction with the different metals. I was told that if I use stainless steel washers in between I shouldn?t have any problems. Please advise.
