> I am getting ready to put up another 5L 20M yagi (not rotational at this
time) for the purpose of improving the situation to Europe. I have a big
drop off that goes from about West to about 20 degrees going clockwise. At
about 45 degrees (toward Europe), I might as well be on flat ground. At
some of the lower angles, according to HFTA, the stack pointed at about 10
or 20 degrees shows as much as 8-10 dB improvement as compared to the same
stack pointed at 45 degrees. The question is this. Would it make sense to
skew the lower antenna about 20-30 degrees North of Europe to best take
advantage of that drop off when these are in phase since according to YO the
free space pattern would indicate a drop of about 4 dB if the antenna were
turned off by 30 degrees?
