Lots of dipole calculators on the net. The total length of a center fed
dipole is 1/2 wave, and that's the magic number.
If you are operating at 14.300 and you're trying to end-feed a wire that
is 32.7 feet long (same length as a dipole, but *not* fed at the
middle), the impedance will be very high.
Add 16.3 feet, and you won't be a half-wave, you'll be 3/4 wave long,
and the impedance at the end should be well within the range of a good
tuner.
Double the length, and you're at a full wave, and it's the same
impedance (more or less) as trying to end-feed a half-wave.
Doesn't matter what you do, if your "randomly chosen" length turns out
to be a multiple of one half wave on a frequency you want to use, then
the stock tuner in most any radio is going to have trouble tuning it.
