Wohne which recommends a roof antenna on the outskirts of the DVB-T transmission area. Have been 4 different internal antennas (eg Clixxun and what etc. with 36dB gain) and tried a maximum of 4 channels receive (often with signal breaks). Had now decided to try, an outdoor antenna and chose the Philips SDV 2940. And I'm thrilled! Even inside I receive now 15 stations in good quality and outside the window all (!) DVB-T channels here in the area. And at a special price (even 6Meter antenna cable and bracket is). So can only express my recommendation!
