Hi Richard

Isnt there a difference there? (I'll admit I dont think in these terms.
I use the actual pattern instead)

Isn't F/B a comparison of "forward" vs "backward" at the optimum/best
case "single angle" and Back Rejection (or some other name) the
comparison of all radiated power forward vs backwards?

Many parasitic designs end up with very good F/B but as soon as you go
off a few degrees a rearward lobe comes into play.
