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?
