Help! TV the 1000th – For dummys :/

Hello! I’ve only had my dick for a few days and I discover new functions almost every day. Today I discovered that I seem to have TV reception! However, only “snow” is to be seen. For this reason I assume that an analog receiver is installed. I tried to read a little bit here via search. Alleridngs are the threads so confusing and partly outdated that I have only become half smart. Is it enough to get this thing running when I buy an ampire DVBT200 and the Dietz adapter cable? Or is there something missing? Sorry that I am so stupid in the relationship instead…. VG Olli
