I thought I would create a thread where we could discuss OTA and Diplexing since I'm sure it may come up in reference to the AM21. I do already have a question that is semi-related... I know I can't diplex OTA on my WB68 and I have a home run from my OTA to each room that has an HR20  in my house, and I don't have SWM yet. My question is can OTA be diplexed into a Cable TV/Internet run? I'm currently looking into dropping DSL for Cable Internet and I'd really rather not have the cable guy run a whole new cable to each room. If I could diplex it with my existing OTA runs that would make life easier on me and the installer.
