Hi Don.
I think you misunderstood me, because with my suggestion you will have 3 SO-239 conectors, but you have the choise to use two of them for a ballanced feeder. That should give anybody a good flexibility.

Martin,
Actually, for my part the 3 SO-239 connectors offer the greatest flexibility. If a user uses open wire feeders, he likely already
has a balun connected to those feeders. To move that balun inside the tuner makes no sense to me. In fact, I have an MFJ 962D tuner that I removed the internal balun just so I could connect a 3rd SO-239 connector. The baluns live at the center of my antennas or at the end of the ladder-line (which is not in the shack).
73,

conductor and SO-239 connector 3 senter conductor a balanced input.
