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. 73, Wayne N6KR > On Sep 29, 2022, at 4:05 AM, Rich WC3T <r...@wc3t.us> wrote: > > Interesting idea. > > 72, > Rich Hurd / WC3T / DMR: 3142737 > Grid: FN20is > Bureaucracy is always in search of self-preservation. — AA7BQ > >> On Sep 29, 2022, at 04:14, David Gilbert <ab7e...@gmail.com> wrote: >> >> >> Has anyone ever tried to used two AX1's back to back as a vertical (not >> horizontal) dipole?
