With the Carolina Windom, the most vertical radiation is found on 160m,
where the thing acts like a short, top loaded vertical. The ant is fully
bandswitching, and will load on some bands without a tuner. The main
drawback is the limitation that applies to all horizontal antennas, and that
is height above ground. Most horizontal antennas are substantially cloud
warmers at less than 1/2 wavelength height.
