Although the device has my television picture not particularly improved (if at all only minimally), but I'm grateful to have it lying around today after a move. On the second connection I can now operate a small tube TV so in my little hobby room. Port 1 is also successfully used it. On this a 4 compartment shielded cable depends really brings something for the image quality and through the wall into the bedroom leads to TV number 2. Oh. I have purchased the equipment originally envisaged because in the old building in which we lived before the cable Germany image on a very poor transmission power and constantly flickering, had dropouts and Plopper (transmit power over KD Reciever requested). I thought I can but with the unit slightly entegenwirken breath cooking. The miserable KD Customer Hatt only then anything advanced although there yes about 1 year ago also went smoothly and the image never had dropouts and wanted no Aussendienstler by email. They threatened me so that I would have to pay to use himself and told me to buy myself a decent antenna cable. Finally, the technician came but then, turning a bit to a few controllers and the image was perfect again. He said it was due to the storm that a few days before had raged over our region :-)! Still not a bad buy described above.
