Open-Folded W8JK Antenna for HF

Originally designed by John Kraus, W8JK in about 1940, this antenna has some interesting properties.
The W8JK antenna is 2 (Two) centre-fed double-dipole fed by a pair of anti-phase signals. Small size, simple antenna, offer nice performance but need a tuner. Tested in this project from 30m to 6m bands
