Amphenol CO-174SMAX200-002 Black RG174 SMA Coaxial Cable, 50 Ohm, SMA Male to SMA Male, 2'

These cables are just what they say they are. I've included a pair of photos with this review, showing the logmag (loss) of one of these 2-ft cables with a sweep from 50kHz up to 1GHz, with a vertical axis scale of 0.1dB per grid line. (My VNA loses accuracy above ~ 1.5GHz so I didn't run the sweep further.)As you can see, the worst loss was merely 0.51dB.Quite acceptable for such a narrow gauge cable! (2.6mm outer diameter, if that's useful to anyone)

Good Quality cable and connectors. Works as promised. No issues
