• The Ugly MacGyver 6 meter J-pole Antenna - Essentially, a J-pole is a 1/2 wave resonant antenna connected to a quarter wave matching stub. The feedline is connected at a point on the matching stub that is at the feedline's characteristic impedance. The result is 3/4 of a wavelength on one side and 1/4 wavelength on the other side.
