TT:
In my experience, variables in the immediate antenna environment play a greater
role in impacting resonance than the presence or absence of insulation on the
antenna wire itself.
The 'keep it simple' approach: Measure the distance from finger tip to finger
tip,
with arms outstretched using a tape measure. Mine is 5' 6". Using 5.5', I
measure off the correct wire length using 234/f or 468/f, add 6' for ends, and
make up the dipole or vertical (If it's an inverted vee, add 5%). Usually it
requires that I fold back the ends a bit, to bring the vswr center where I want
it. Haven't had to add wire in longer than I can remember.
