A better way to describe these is that they are an off center fed vertical
dipole. No helical loading. They are working on a 40 ft version. I'm seriously
considering a 28 ft one over salt water. Tuner at the base.73,Gary K9GS

Performance?Hi Steve,The website describes these as vertical dipoles. That
suggests that they are helically loaded. Vertical dipoles don't need radials.
They can center fed or off-center fed. The tallest of these flagpoles, at 28
ft, could work fairly well on 80M. An important caveat though -- field strength
from vertically polarized antennas is strongly dependent on soil conductivity.
That is, the better the soil in the far field in direction you're trying to
work, the better they work.73, Jim
