Not counting the potential tuner problems you mention, my experience is
a 102” whip with no loading will work ok on 10-20m, but on 40m and below
it sucks.

with no tuning? you get acceptable match to your rig without a tuner,
would you explain more?
thanks

I just re-read your statement. Are you saying the whip without a
loading coil used thru a tuner? My first thoughts were you meant
without a tuner.
I expect that 40 and below will be a bit poor. I hope to find a
compromise of sorts where I can add a loading coil, but only change it
when I want to operate 40-80 meters, sort of a switch between the
higher and lower bands as opposed to setting it for each band. The
alternative may be to have two antennas, one for the lower bands, set
as needed per band, and one for the upper bands that only needs tuning
with the tuner. If I am lucky, I may be able to have one with a
loading coil that tunes all the lower bands relatively efficiently and
the whip for the upper bands. I can deal with two antennas, I have a
switch but my problem right now is I have separate 40, 20, 11, 10, and
6 meter antennas. If I want to change bands, I have to replace each
antenna. Likewise, if I want to add a band, I have to buy more
antennas. I just want to simplify my operation for when I am mobile.
I have a 135 foot dipole with 300 ohm feed that I can toss up in the
trees for portable operation when I want to be efficient or for
emergency operations, but for moving, I don't want to pull off the
highway and get out of my car to change antennas every time I want to
change bands.
Thanks for the input.
