You may have to show me where he says "BROADCAST" or wireless.

He says transmit, which is also applicable to sending a signal over wires.
He then said

He also specified that there is no F connector on the TV.

I have never seen a TV that has no antenna or any way to connect one.  That
would make it pretty useless.
Even if it just has a broken single extendable antenna, he could connect the
wire to it to get the signal in.  It would not be a proper impedence match
but would most likely be more than good enough.
