Visually, the device looks good, but you should not dislike piano finish and also some space next to the TV have free compared to small passive antennas, this model here that is a bit larger. An empty socket for the power supply should be as stated also available. Otherwise, the port is working actually as with all other antennas and probably represents anyone with an unsolvable task. Channel information ultimately settled on the TV or the receiver, the antenna itself is connected only once and a bit aligned ready for best reception.
Another note: While in the description or on the packaging, that are also promising HDTV channels can be received, this is only a theoretical statement for German users. Because in practice, no HD channels in Germany are unfortunately broadcast via DVB-T (and can therefore also not be received) is not changed by the antenna model nothing.
