Default 10m - 40m non resonant vertical

Dear group,

As a temporarily solution I would like to use a cheap 5/8, 6/8 or 7/8 WL
commercially available CB antenna as a non resonant vertical with elevated
radials for use on 10 - 40 meters tuned by an automatic remote ATU at the
base of the antenna. I used MMANA and EZNEC (demo) to calculate the
expected impedance for the frequency range and found too many results for
the height of the antenna. Now I am confused about what to select.
Is 5/8WL on 10meters a good height or 8 meter (22')?
What I want is a low take off angle on 20 and 30 meters with high
efficiency and an impedance which my remote ATU can handle.

Fred, PA0FVH

Obtain a Solarcon A99. It will behave exactly as you have described, even
with a built-in tuner. BTDT. Put it up about 20'. It will suck on 40 meters,
but it will work. 20 meters isn't the best either, but it is usable. 17
meters on up it will work very well.

With 100 watts I could work 15 & 17 meters into Europe from NJ in the USA,
with headroom to spare. Yes, the bands were open, but they were crowded at
the time. I worked Austria as though they were next door.
