Did some dicking about with the VNA today and tested the rf coupler i built. Not sure how i interpret the data, but i have it LOL
The through port return loss. I figure what this means is from 1 to 100meg the through port has a quite flat frequency response.
Port Isolation. I figure what this means is i have a coupling factor of say -18db or near enough. I might have to rebuild it with some more turns, I was looking for at least 30.
