Hello, I have spent a few hours trying to read up on my particular issue and want to clarify my understanding. I'm trying to add 3 modulated signals into a whole house system. The ssytem has a TERK BMS58 with a single coax going to each TV where each has an HR24. If I add the modulated channels coming from a ChannelPlus 5445 into a combiner (combining with an antenna) then into the OTA input of the TERK, is it correct to assume I will need filters to prevent channel overlap? At each HR24, do I need to use a diplexer to pull out the OTA and run to the antenna in on the TV's? Is any of this correct?
