There are some issues with the ionoshere that affect verticals and dipoles
differently at MF, as opposed to HF. EZNEC doesn't even claim to model
those effects.
I put up a full size dipole at 16 meters high for a year and A/B'ed it
against my vertical. The dipole was always 10 to 20 dB worse,
except for an occassional local station. I am in a high ground
conductivity area. Other stations have has different experiences.
