I happened to be down at Harbor Freight yesterday and noticed they have
20-foot telescoping aluminum flag poles on sale for $55. That should
make a good vertical on 40-10 meters (almost 5/8 wave on 10) with maybe
a little bit of top-loading needed on 40. It even comes with an
American flag. :=)

I hope you have serious top loading.
I have a video of a base loading coil throwing a two inch
long arc when running 500 watts

over 1300-miles away (not in the prime DX season).

Paul,
That is not an easy question to answer, and for your particular case, we
do not have enough facts.
It would be necessary to know the configuration of the radial field for
that vertical, then plug that information into an antenna modeling
program to find the impedance at the feedpoint to
Paul, the K2 internal tuner is a wide-range device and should be able to
match the 43 ft vertical from 10 thru 80 unless you happen to pick an
unfortunate length of feedline. The impedance seen by the tuner will depend
on the feedline length.
All of the available 43 ft verticals should work equal
Does anyone have any experience with trying to match one of these 43-ft
verticals, that are being offered by several manufacturers, using the K2s
internal ATU? Is it able to find a match on 80-meter CW? Are there any
particular brands of 43-ft verticals that you like or don't like? Most of
