Of course the best of both worlds is to have a crossed yagi with a phase

Jeff, I want the" best of both" worlds but before one jumps one needs
to know the advantages and disadvantages of both first. To be frank, I
do not know what happens to all signals when they are reflected
including the reflection off the ground to a receiver or a direct hit
on the receiver from our upper layers so I have no way of undertaking
a comparison. Now most hams are resistant to change or will only
follow the majoratory thus the questions "who has the majoratory". For
me I see CP as an ideal approach for smaller volume antennas which is
the "holy grail" for hams, but one has to determine if smaller is
important enough to overide possible faults.Now I have a whip antenna
( no ground plane) on my tower that is CP for top band but the bands
are poor it is difficult to determine its worth especially since
there are no similar radiators out there. So I fall back and ask for
"what is known already" as there is no point in re inventing the
wheel. Is that so bad?
Now before the catwalling about the possibility of having a whip (a 5
foot pole) for top band
my intention is to release all that during the next month. So lets not
waste energy in side tracking comments and stay on the essence of this
thread. Remember the last time I intended to release it was evident
that most did not want to hear it........ so I went along !





Commercially (terrestrially) I don't think that CP is used much except
perhaps on microwave point to point links.
