Watch live tv?

I got a television as a gift and I mainly use it for netflix because I would like to watch live tv, for example sat 1 or prosieben but that doesn't work because I don't have an antenna or receiver and I don't want to have that any other options such as a stick or something?

Assuming that it is an older television set, the only option is likely to be to connect a set-top box for the intended reception area, e.g. For DVBT-2.

Is a newer device

Do you have to search (manufacturer!) What equipment is available: DVB-S, DVB-C, DVB-T, DVB-T2, analog…
