Baluns and UnUns

This page contains some balun / unun / impedance transformers which I have built. This page is still being built.

Impedance Matching

Current (choke) Baluns

  • 1:1 Choke Balun – For use as a ‘tuner balun’ on the output of an unbalanced ATU for feeding a multiband doublet.
  • 1:1 50Ω Choke Balun – Built with coax, to keep the impedance at 50Ω for feeding a coax fed half wave dipole.

Voltage Baluns
