"NettetYou'll need some form of inductively coupled ("link-coupled") tuner to do this. The most popular of these at the moment seems to be the "Z-match" - it has good although not perfect current balance on the outputs. Most of the Z-match designs I've seen can be implemented with two variable capacitors, and one fixed inductor. There's a "two coil" " - Link coupled tuner
