I've seen some car radio whip antennas that look like they have a wire wrapped

My antenna on my minivan is like that.
I think the supporting whip is fiberglas/or some insulating material,
and the wire is the actual electrical element; and in the interest of
saving length and providing strength, they wrap the wire around the
slightly shorter antenna pole. *The wire is then connected to the lead
of the antenna. *It works fine, about as good as a metal whip of
similar length. *Antennas for cars are pretty uncomplicated
critters... :-)
I can't believe I have never seen that before. Wouldn't there be a
chance for eventually the wire to work itself free, is it glued or
clipped to the whip?- Hide quoted text -

Picture a thin pole (the whip) with a very gently coiled wrap of wire,
a turn every inch or so, from top to bottom. *Then, the entire thing
is covered with a wrap of something like shrink-wrap to hold it
altogether. *Unless the antenna is traumatized, the wire is pretty
much set for life.- Hide quoted text -

Yeah OK, you didn't mention that is was encased, I thought it was
flowing freely in the wind, my post above mentioned what you just
said. ;-)
