If you connect a cable to the TV socket in the wall and the other end to the laptop, can you watch TV on the laptop?
That's fine.
You need a piece of hardware for this, depending on what kind of TV connection it is. That's it then.
The streaming offers are an alternative.
You can't without a tuner in between, your laptop doesn't have an antenna input either
Then describe where and how the antenna cable has to be connected!
No, it does not work out this way.
But on this website you can watch TV channels as a stream: https://www.2ix2.com/ You don't have to install anything.
