sorry radio, I didnt see the freq numbers. Someone said something in the string that makes sense. If it is dish then I suppose the return could be over driven by the low frequency that the second receiver is using. I would try padding the output of the dish receiver that feeds the second tv. I would love to put my analizer on the line and see what the numbers look like
