My example is an HF9V multiband vertical mounted on the back of my shed (on
a side where a gutter would normally be, not on the peak) around the 6.5'
mark AGL.

I then made 2 RESONANT (raised) radials for each band I intended to operate
from. 80, 40,30,  20, 15*, 17, 12 and 10m.

Yes, and in the study that I published about ten years ago showing that HF verticals work better when on the roof of a typical home, that's exactly what I recommended. It was a solution developed long ago by others.

Most of what I write is with the goal of helping others UNDERSTAND how stuff works, so that they can make intelligent decisions about using that "stuff." Most of the responses in this thread from others had the same goal.

Folks who are bothered by this might try getting Tower Talk posts as individual emails and use their delete key!
