These cables are exactly what they say they are. I have included a couple of photos with this review showing the logmag (loss) of one of these 2 foot cables swept from 50kHz to 1GHz with a vertical scale of 0.1dB per grid line. (My VNA loses accuracy above 1.5GHz, so I didn't sweep any further.) As you can see, the worst loss was only 0.51dB. Quite acceptable for such a narrow cable! (outer diameter 2.6mm in case anyone needs it)
