In my case, a Panasonic DVD recorder so beamed from the TV reception that various channels were no longer be received once the Panasonic equipment was turned on. Now I have two of three cables in my building (the signal is passed through digital receiver and DVD recorder to the TV) is replaced by two purchased here Systafex cable, and all channels are again receivable. The immense image disturbances that occurred at the analog ARD image since the intrusion of the DAB + radio signal are almost gone. (Although I do not even analog, but for testing purposes, it speaks of course for the good shielding of the cable.)
On a single HD channel on the top frequency range there is still too occasional disturbances. I can not rule out, however, that this is due to the first long cables from a different manufacturer, which through the living room leads from the antenna port (or weakening the overall cable signal in my loft).
Overall, I am at this price very satisfied with the Systafex cable.
