That's not gold, it's copper over steel. The better stuff is solid copper, but there is not and never has been gold in any RG/6 coax.
For the antenna; as mentioned, the winning antenna by far is a Batwing/ Wingman, or the new combo. The Razar or Jack simply do not perform as well.
One thing I'm also trying to point out in these antenna threads is the FCC is about to "repack" the entire television spectrum with the intent of retiring off the air, as many stations as possible, and/ or moving them BACK to VHF. Haven't looked at the Razor, but the Jack is a particularly poor performing antenna on VHF. The Batwing is BY FAR a better antenna on VHF
