I have a home CCTV configuration set up with 6 cameras, Channel Vision modulators inserting channels into my cable. I am trying to add cable modem access but when I splice it into my system using a 2-port splitter it fails. I am splitting it at the main feed for the cable and as soon as I connect my system to the splitter the cable modem goes down. Could my cable signal be that week that when I connect a third device to the splitter it drags the signal down? I also have a Channel Plus LPF470 Low-Pass filter at the cable access point that seems to block the cable modem signal that I have removed for testing. Question: does a 2-port splitter still lose 3.5db if only one device in/out is connected? Any ideas/comments on this configuration?
