Hi John: When HP came out with the first VNA (8410) I attended one of the demos. Part of that was testing a BNC cable over the microwave range. It worked much better than I expected. It turns out that the cores of a type-N, TNC and BNC connector are all the same and they will properly

Hi Broke, I think it stays not to discussion, that a better BNC can be usable up to some GHz, but the longtime life cycle is ( through often using impedance changings/unsure contacts) _I think_ clear worser as TNC/N... Have good time! (Im over longtime time-nuts reader ) Karesz 2010/3/26 Brooke
