The point of the discussion, and the links I included,
show that a modest horizontal loop has the same dB gain as a dipole AT
THE SAME HEIGHT. The loop advantage is that the dipole performs optimally
on its fundamental and harmonics ONLY, while the H-Loop performs equally
well on all frequencies at and above about its one wavelength

circumference.

Well said. A horizontal dipole is optimal only between 1/4 wave to
preferably 1/2 wave height above ground. Anyone who thinks erecting a
horizontal loop at 1/2 wave height is easy, we've got a bridge in Arizona to
sell you. These horizontal loops are used, but they are typically strung
between the tops of several tall telephone poles erected in a circle.
Nothing you see in a hobbyists backyard.
