A Versatile Tuner for SOTA Activations by KX0R

Hi,
I plan to build the tuner by KX0R, the larger one. Which lengths of wire and lengths of counterpoise work good for which frequencies?

From the reading, I already got:

  • 66 ft, no counterpoise => 7, 10, 14 and 21 MHz
  • 52 ft, 12 ft counterpoise => 7, 10, 18 MHz
