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

Auto makers went from Telescoping Whip Antennas
to Solid One-Piece Stainless Steel Antennas because
of lower Cost and greater Durability.

The Fiberglass Rod with Wrapped Wire Whip Antennas
were done for the same reason : lower Cost and greater
Durability; over the life of the Car/Truck.

I spent 33 years at General Motors Product Service Engineering and I
can tell you that on General Motors vehicles the wire wrapping on the
antenna is there to break up the air stream around the mast so it
doesn't whistle in the wind stream.
