Hi Mike,
It was good to meet you for the first time this year in Dayton, I enjoyed our
brief conversation in the flea market.
I've had exactly the same experience with off brand BNC cables and connectors.
I long ago placed them in the trash! When you get used to the normal mating
tension in a good quality BNC connector, you will soon recognize bad ones.
