[Elecraft] AX1 dipole

A vertical dipole does not need high above ground to work well.  A good shortened 160m antenna is a vertical dipole with the ends pulled into a C shape to reduce the height.

We studied this. To provide any advantage over a vertical AX1 with a single counterpoise wire, an AX1 dipole would have to be well over a quarter wavelength above ground, with both halves tuned to resonance, and fed with low-loss coax and a balun or balanced feedline. Even then the advantage is small and only in the dipole's broadside directions.

That said, a pedestrian-mobile version of the dipole held a few feet above the operator's head would eliminate the dragged counterpoise. I'd be concerned about nearby trees and ogling passersby.
