The wire is the actual antenna. Wrapping it around the the stick, which is for support, allows the antenna to have the length required without sticking in the air so far. Some antennas have a coil on the bottom or middle which does this.
Why do cars no longer have antennas?
Shark fin-type car radio antennas have their limitations. Because the space inside them is very tight, it is not possible to cram many antennas inside. Integrating them into the rear windscreen has its limitations, too. And obviously, it would be impractical for cars to have satellite dishes on their roofs.
Do you need to remove antenna for car wash?

How do you remove antenna wire from car stereo?

How does a shark fin antenna work?
Each band or system — FM radio, AM radio, GPS, cellular — uses a separate antenna. There may be separate window traces for FM and AM, and antennas in the shark fin for GPS and cellular. Or, they may all be stuffed in the shark fin — if so, there’s often a short aerial protruding from the fin.
Is it safe to go through a carwash with an antenna?
Automated car washes have a poor reputation for damaging the flimsy or exposed components on your vehicle. Mirrors, the antenna, your paint job, and your wheels are particularly susceptible. When the brushes push against the side of your vehicle, your antenna can be bent, snapped, twisted, or pulled off.
