- Another conductor is placed slightly above a half wave dipole and connected to it at the ends
- Has the same radiation pattern and a broader frequency response between the 2:1 SWR points than a single wire dipole
- Feed point impedance is about 300Ω so it is a better match for 450Ω line than a single wire dipole
- Will not operate on harmonics of its resonant frequency
- Feed point impedance can be modified by varying the diameter of the conductors and their spacing
