I must agree with the polar bear, except step 3. I have a Grundig 32 VLE 5401 BG, Cabel receive ATV + DVB-T. The latter on the menu> Antenna the antenna aktiviertIst disabled in the menu, I can only C-ATV see u. Not DVB-T. In other words: Disabled ON = current, activated = stream. C-ATV can I see with both settings. Whether DVB-C requires power at the antenna I do not know - I know it but, if you out of curiosity.
