After hooking up a CM4228 I can no longer view any Voom! I also have 0 signal power for all of my locals, although I can still watch one of them. This is with both lines going through a diplexer. I assume removing the diplexer would give me back the Voom reception, but would this straighten out my OTA issues? I could receive 2 channels with high signal strength with only the unamplified Winegard antenna.
