Is it really necessary to ground the satellite dish itself to a grounding block? Wouldn't the RG6 cable be enough when going through the grounding block and connected to a cold water pipe? Wouldn't that take care of any static charge built up in the line from entering the receiver? BTW: Where is the best place to put an (inline amplifier, gounding block, multiplexer) between the dish and the receiver? I'm thinking from the dish; inline amp then grounding block then multiplexer all within 30' of the receiver on a 100' line.
