[AtLarge]

Is every distribution block on the line supposed to be grounded? I have a Mediacom cable line coming into the house that is grounded to a piece of conduit on the inside of the house. (It is only for the DSL modem now) I have coax going from the attic antenna down to the basement and three distribution blocks on that line including an amplifier. None of those are grounded. Should they be and how well? I can put a rod in the ground outside and run a wire in to connect to the first 8 output block. Another 4 output would have to ground to the same conduit running around the basement ceiling for lights. The third one is probably too far to ground unless I jumped off an outlet. Would this be overkill or unnecessary since the chances of the attic getting hit by lightning is pretty small?
