So, help me here.

Let's say the DirectTV dish is on the roof, and it has a coax cable that
goes down the side of the house, through a wall, to a wall plate.

From that wall plate, how does "it" (i.e., the tv signal) get on my
"network"?


I think you're looking at this the wrong way. The signal from the
sat dish goes directly to the DirectTV receiver. The TV is connected
via HDMI or component video to that receiever. That's one source
of content that then can be selected for TV viewing. The receiver
also has an Ethernet or wifi network connection which can be used to
access additional streaming content off the internet as an additional
video source.



You said the tv signal gets into the network via either the wireless
connection or through the wired ethernet (cat5) cable.

He didn't say that.


But, how does that coax cable tv signal get to either one of those (i.e.,
how does the coax connect to the wifi or the ethernet cable)?

It doesn't. See the above.

That's how it connects for one TV. There are options that use a wireless
bridge to connect more than one TV, but that's a further complication.
The above is the basic setup.
