Except at Art Bell's compound.

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. Jack |
