This is a project to design and build a Guanella 1:1 (current) balun for use on HF with wire antennas and an ATU.
First part in the series…
- Design / build project: Guanella 1:1 ‘tuner balun’ for HF – #1
- Design / build project: Guanella 1:1 ‘tuner balun’ for HF – #2
- Design / build project: Guanella 1:1 ‘tuner balun for HF’ – #3
- Design / build project: Guanella 1:1 ‘tuner balun for HF’ – #4
- Design / build project: Guanella 1:1 ‘tuner balun for HF’ – #5
- Design / build project: Guanella 1:1 ‘tuner balun for HF’ – #6
For use with a tuner, the most important design criteria are:
- high voltage withstand;
- high common mode impedance;
- generous power handling given our 400W PEP limit, possibly 1kW in the future.
