A cable qualiy

I had a bad reception with a cable to first prize and I was missing strings. When I plugged the armored cable reception quality has improved and I added more elbows. It is then a restart channel search.
I was told though a shielded cable did not affect the quality of reception ....
This cable is not as flexible as the first cables price and that's good.
I must admit that the price is a bit excessive (3 stars) and you can find cheaper.
I suggest avoiding cables first prize and I am satisfied with my purchase.
