A couple of things to keep in mind ... RF flows on/near the surface of a

length of an antenna made from insulated wire will
be slightly different than the formula-calculated length.
-------------------------------------------------------------
FWIW a horizontal dipole using plastic covered Flexweave cut to the
formula-calculated length is roughly 2-1/2 % too long at 40m and 3 % too
long at 6m when in the clear and a half wavelength or more above ground. It
needs to be shortened if it has to be resonant at the working frequency.
