This will prevent the possibility of earth loop interference being introduced into the antenna feed. In Brian's case it would be more convenient to apply an earth to the receiver's chassis if it hasn't already got one. I wouldn't worry about a direct lightning strike on the dish as a thin earthing wire attached at either the LNB or receiver wouldn't do much to prevent it frying the LNB, aerial cable and associated receiver!!</blockquote>
