Getting ready to buy a RF Video Distribution module for my SMC, and have a bit of a question. Based on my research, I tentatively plan on using a Leviton 3x8 distribution module. Input to the distributor will be the cable feed, an off-air antenna, and a modulated input. If I understand correctly, all three signals will then be 'combined', then distributed to each location via a single RG6 run. Question is this: How do I split the cable and off-air signal at the drop? Cable box needs its own discrete input, as well as my TV for off-air...? Hope I'm making sense, and thanks in advance!
