Hi Richard,

Then that is dashed by his having trimmed the ends (presumably
everything at the same height, and as such in a direction away from
earth) and the multiplier shrank more. More likely the capacitance
between the ends grew instead (corresponds to all factors observed).

Now THAT makes sense! I was worried that at the rate
I observed the nnn/f formula decline, your average 10m
dipole would be stupidly short!

And, for the record, I never touched the height of the feedpoint
or the angle of the legs. Instead of tying to the tips of the legs,
I attached the guy lines (heavy duty natural twine) about 8" up
from the ends. That way, I could trim the ends without having
to redo the supports. I wrapped the twine around the ends to
keep everything straight.

So, only 2 things changed - the height of the ends (10') and the
length of the legs.

Thanks everyone for the ideas.....
