    20m 1/4 wave vertical

    The 20m 1/4 wave vertical, when installed over a good ground structure, will outperform a 1 /2 wave dipole at 1/4 wave above ground for radiation angles less than 30 degrees. Even a shortened loaded vertical similarly installed, will still outperform 1/ 2 wave dipole at heights lower than 1/4 wave for radiation angles below 30 degrees. It is relatively easy to have such a ground set up with just a few elevated radials.
