Technically yes, that’s possible. Friend of mine runs such a setup.
You would be restricted to the basic, non encrypted channels. DigiCard doesn’t work with that.
But with a RF to IpTv converter it’s possible. But mostly you have to setup that yourself. There are tutorials in YouTube about that subject.
I would say, it’s probably easier to set a cable to your Tv, than setting up such a setup.
But if you see it as a challange, it could be interesting.
