How so? Even a 0.5 inch cross section the length of a shortened 40m or 80m antenna adds up to more area than the cross sectional area of a coil, with a greater percentage of it up high where the leverage is greater. And as someone else here said, it is easier to build a strong vertical out of aluminum tubing than any kind of insulator that would be required for a helically wound antenna.
