Poorly made Quad Shield cable, can't beat a well-made cable as this one. Poor ends will do more harm than 3 vs 4 shields. I approve of this cable, as they seem well built especially the ends. As for noise Earth ground hook ups on the antenna gives more noise cancelling and aids the reflectors to do their job! For note: chicken wire (outside) or foil (inside) on the reflectors seem to increase signal strength, by far large parabolic reflector anyone? (Yes, you can go nuts with this one and gain maybe a little more) disclaimer: Outside more stuff on the reflectors may hurt durability (mine is inside with cheapo foil)
