After moving into our new apartment we unfortunately had to see that cable digital TV channels are found barely. In addition, the search results were after each pass otherwise. Even the channels found were high partly shockingly bad (blocks, etc.). After we had the 08/15 antenna cable from the electrical market (3m / 1m) replaced with shielded cables, all quality problems were actually eliminated and we have since totally satisfied. The purchase of these cables was a pure act of desperation. I must confess that I (previously) have always responded with reports of HiFi freaks gold plated cables and similar miracle cure with a shake of his head and a strong relationship saw the esoteric. At least with antenna cables I now disagree.
Who has good reception, you should give it up. For all other the significant extra cost is worthwhile.
