Since the cable offensive we had in the apartment building with KDG connection, increased formation of small blocks and Tonausetzer. Kabel1HD, ARTE HD, Vox HD, NatGeo HD, Planet HD, Pro7 HD sometimes ... At first only occasionally and tolerable, then more and more intense until finally unbearable. S02 / 03 problem, dropped out due to new construction. WLAN, DECT ... diverse 90-100 dB Kabelchen ... signal amplifier ... no improvement. This tuner here who helped the only! The problem transmitters of 55/65 to 85/95 ... absolutely no more noise. Installing, finished. ARD stations required new search, that's it. Supplier was fast and reliable. Thank You.
