A Balanced Balanced Antenna Tuner
- A balun should have about 4 times as many reactive ohms as the resistive ohms of the load, this means that for use with a 600ohm balanced load, the balun should have a secondary winding reactance of about 2400ohm/

HF-6M Antenna Tuner Preselector- Frequency range: 2Mc...52Mc 180m band depending on the mismatch of the antenna used and-or maximum inductance, experimenting with the coils can be desirable
HF Automatic tuner- The atu is composed essentially of relays commanding inductors and capacitors
I built a ZM-2 QRP Antenna tuner- The Emtech ZM-2 Antenna Tuner is a nifty little portable transmatch for QRP
Informationen zum Z-Match Koppler_Selbstbau- The Z-Match coupler is a popular balanced self-assembly coupler, the circuit diagram for the individual components looks like this
