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

Does this help reception? Is the coil attached somehow to the car or
just the antenna itself?

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... :-)


It adds inductance.

I think the Fanfare antenna has such a special spool that ? makes it better
?.

Really? That's a pretty loose coil on those things, how much
inductance can it have? And frankly, do the auto manufacturers
actually *think* about things like this when car radio technology is
already so implicitly satisfactory?

We are talking about the same thing, right? Just a loose wrap of wire
on the nonconducting whip core vs. an actual compact coil?
