Being a topband mobileer for many years I am used to using antennas that are a tiny fraction of a wavelength. From an experiment I once did to try to improve \"sky-wave\" from the whip, I can well believe there will be a noticeable difference between a true vertical and an inverted L. Whilst in QSO and I tilted the whip over to an angle of 45 degrees which improved the signals slightly over the short sky-wave path. The difference between LF and topband of course, is the launch-angle required to make the best use of any skywave. I will set up some vacuum relays to switch my antenna from T to L configuration soon. Then I will bore everyone asking for comparative reports! It will be especially interesting over long paths. 73.
