Need facts about USB TV Tunner
Im looking to buy a USB tv tunner, and i was just wondering if you need anything extra, that doesnt come in the box. I was reading something about needing to be plug in with an Antana, however this is a desktop which is in my room and there is no way i can get an Antana is here.
Is there something so i can just plug the USB in not need to connect to my living room Antana?
Also how much do they usally cost
