Uh Richard, (clip)


If the loading coil used to resonate an electrically short vertical
really contributed '"electrical degrees" arising from some
attribute(s) of the coil that made the short antenna system the full
electrical equivalent of an unloaded, 1/4-wave vertical, then please
explain why the loaded version does not have the radiation resistance,
and typically the radiation efficiency of the unloaded version.
