I have a question on grounding and hope some of you guys can answer me. Right now I have copper grounding wire running from the dish straight to the ground. However, I read somewhere that you must also ground the RG6 cables. Right now I have RG6 running from the multiplexer on the dish straight to the receiver. RG6 from Wingard GS2000 straight to the amp and to the receiver also. Is it necessary to cut these 2 cables into 2 and put a ground block in between and ground it? If so, will the signal deteriorate?
