Location: Hamburg, Norderstedt outskirts. The small August DTA400 geploppt via suction cup to the window, connect the cable to your TV (Samsung UE40H5090) - in no time found the television about two dozen interference-free channels; the general, nationwide radiating main station, next to a few regional.
Trouble-free is, of course, no HD, but otherwise everything was perfect, good colors, good sound, no stuttering or Blöckchenbldung.
So uncomplicated with no additional equipment or cabling - I'm thrilled!
