I am cable Germany customer and have been since late 2009 digital cable television, and it was so far received without problems. In early July 2011, there were suddenly reception problems with the digital programs of ARD (Das Erste, WDR, SWR, BR and HR), ie the receiver reported "Note 2 -. This channel can not be received Please check your antenna connection.". The third program I could still see, but the image quality was always pixelated. Before I called the hotline of cable Germany, I looked around times on the internet and came across the following page: [...] So the problem is known. The cable Germany hotline confirmed that it may be due to the old antenna socket 1995: "At that time, digital non-issue even though the old doses have thus now problems!". The old antenna socket was replaced by the Kathrein ESD 84 (stab or terminal box). I can now receive all the programs without any problems! A high pass filter, [...] as described on the page, I do not need! The signal strength (can be in the channel search in the receiver's menu read) is now thanks to the new can also be much higher! I can only recommend this antenna socket !!!
