http://www.ronard.comychim.html. I recommend all new RG-6 coax on the outside. And replace any other coax that might be bad with new RG-6. If only one tv is connected then the coax from the HD7696P antenna goes to the one tv , No splitters , if 2 tv's are connected then use 1 two way splitter. If 3 tv's are connected then use 1 three way splitter. Do Not string splitters one after the other , every time a split takes place the signal is reduced. . How many tv's are/will be connected?? Here are some places to buy antennas and etc. ,
