This cable does not bring the desired success. According to a local radio or television technician master, which I presented to the cable that is not a 4-fold shielded cable with 120dB; it is much too thin and not wearing a print out of which would the specification. He told me (initially on loan) a real 4x cables with 120 db provided the improved TV reception as they had hoped. Finally, I have returned the wrong cable to Amazon. I am outraged, especially since I still have to bear the cost of returning (dues).
