No, I didn't mean that.
If sloping ground improves radiation pattern, it's going to be worth
more than 1 db. Pattern changes of any sort typically have significant
effect, whereas one db is almost trivial (notwithstanding my own
experiments on that on my website). I'm not saying that sloping ground
actually has a significant effect ... only that if it has any effect at
all it is likely to be greater than 1 db.
