Another cable on loan from DKak. This is a cable made by Better Cables called the Silver Serpent. This cable is 3ft. long and terminated with BNCs on both ends. It has a nifty white netting over black for a cool look and has heat shrink tubing at both ends marked with the company's name and product name. It also was marked for direction, and I respected that for these measurements.

The TDR measured this as a 75.47ohm cable with little if any variance. Network analyzer measurements have the -3dB point at 8.6GHz.

I've included a picture of the cable end because this is a very common 75ohm BNC. Well, I say it is common, but what I meant was that it is common amoungst the cables DKak sent me. The easiest way to identify a 75ohm BNC is by the lack of any teflon dielectric sleeve just inside the shield barrel.
