Rubbish cable

This cable does not pass the test on a length of 3 meters. While my old cable 3 meters, it is true male-female, plugged into a wall socket connected to Numericable which broadcasts a DVB-T MPEG-4 / MPEG-2 signal received on tuner Akira DHB B36HR 34 channels and 10 radios, this cable transmits only rare channels that receive only 18 channels and no radio. Moreover poor build quality, there detects defects on the ground strap in a white PVC sheath fine. Tested 5 meters black, same comments. Both returned for refund.
