This might be the wrong forum for my question. Please direct me to the correct place if that's true.

I don't use the coax connection in my home at all. Meanwhile, there is a coax jack on my roof in case I ever wanted to put a TV there and use actual cable.

I assume it's possible to mount an antenna on my roof and use the existing coax wiring to connect to the dongle FlightAware offers? Has anyone done something similar?

With the right impedance matching and good coax cable I don't see why not.
