I remember reading a study back some years ago about the benefits or lack
there of, in using a vertically polarized antenna as oposed to a
horizontally polarized antenna for long distance work. It read that there is
little significant difference between the two at the recv end as the F2
layer influences ( for lack of a better word and my memory) change these
signals into primarily horizontally polarized signals anyway. Does it make
sense? Anyone have thoughts on that? -Mike

I operated one of these & learned polarization shift on DX signals.
While on "horizontal" polarization, you'd see a dip in signal strength.
If you switched to "vertical" polarization at the null, the signal
strength would peak.
There is another similar antenna called the "Moonraker". I operated one
as well. Gamma match fed only with 4 full elements horiz & 4 full
elements vertical. Same operation & same signal polarization
switching. The vertical would be used for ground wave & you could
switch between horiz & vertical for DX.
