Gang,
        The age-old question has arisen and I haven't the answer. (What
else is new...?) When constructing a wire dipole with INSULATED #12 wire,
I know that it has a velocity factor that makes it resonate lower than an
UNINSULATED wire of the same length.

        Example: (Using the formula for one leg of a dipole 234/Freq=Feet)

         An UNinsulated wire 16' 6" is 'sposed to resonate at about 14.18
mhz. However if you cut an INsulated wire 16' 6" it resonates lower
because of the insulated covering.

        There was an article on this somewhere. Anyone have a clue on the
difference in resonance frequency that it makes? Is it significant?
