Gentlemen, Measuring the F/B of any HF antenna in the E-Plane only, is
at best a guess. The only true way to know the real F/B is measuring it
in the H-Plane, and there is the problem. Not many can perform that
measurement, unless you have a bottomless pocket book and can rent a
plane / helicopter or just use scaling, of the antenna under test and
that's not likely either. You will never know what the rear lobe(s) look
like w/o that measurement.
GL in your endeavors.
