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.
