Hi Butch,
Well, I do have some good news. I was thinking of the quarter wave formula,
like you said, because each leg of the Dipole is a quarter wave. However,
after sending the Email I kept at tuning the antenna and now I have a
section of 75 meters that is at 1.4 to 1, and the top end of 40 meters is at
1 to 1. I'm smiling.
I have been getting 59s and 58s this afternoon on 40 meters. This even with
the bad band conditions. I am one happy person.
God bless,
Mark WZ0K

What kind of antenna, a dipole? This is for a quarter wave, but of
course, that would be a quarter wave each side of center on a dipole.
Heighth above ground really won't change the formula, I usually cut a
little long just in case. Ground conductivity, surounding objects and
all of that effecdt the tuning of an antenna.
