TV antenna signal over coax shared with cable internet and Moca (alien.top)

So...I have internet via DOCSIS3.1 cable. I have 3 moca adapters connected to provide wired LAN in a couple of remote spots. I need to connect a rooftop antenna to a tuner near the router. I only have a single coax connection, including the roof.

Before I climb around up there and purchase an antenna, can anyone tell me if all 3 signals (cable internet ingress, MoCA, and over the air TV) can co-exist on the same coax line?

Thanks in advance.

HUGE no. That's asking for the cable company to shut you off or come knocking on your door. You would be causing ingress and prob tick the neighbors off too. You'd be injecting AM/FM/OTA TV and whatever else is in the air into the cable system.
