Ok, but I'm unclear about what "improves radiation pattern" means. To paraphrase
your other premise, "I'm not sure if it does or doesn't but if it does, I'm sure
it's big" has me wondering. But I wonder about a lot of things...

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.

I hope you meant much less than 1 dB.

Agree on the coax losses, but totally disagree on both of your other comments:
1. Elevated radials will ONLY help reduce near field ground losses ... they
will do nothing to help radiation pattern. The effects of ground
conductivity determine far field pattern (given a particular profile) no
matter what kind of radials he uses.
2. If there is any gain benefit from the terrain profile at all, it will be
much more than 1 db.
