It sends out signals through the air to a radio tower.
The options for car radio antennas include internal car antennas, external car antennas, power antennas, and satellite antennas. The internal antenna is the least effective and most cars come with either the external fixed antenna or the power antenna unless their is a satellite radio in the car and then it is a satellite antenna.

yes European cars have antennas i own a 1994 golf gti that was made in Italy and it has one
There will be no interference because the antennas are on different frequencies.
Not all radio antennas are vertical.The main reason radio antennas tend to be vertical is convenience of mounting. Many early radio antennas were long horizontal wires strung between two poles or trees. This was also a matter of convenience in mounting such a long antenna (e.g. 50 feet to 100 feet in length).When you are operating radios in the VHF or UHF band a vertical or horizontal mounting of the short antennas used at these frequencies might be selected to improve reception of a polarized radio signal sent by the transmitter.

An antenna is for radio reception. Some antennas are visible and usually mounted on the front right side fender. Some antennas back in the eighties were used for car telephones and CB radios and were not installed by the factory. Most remote starting features and some burglar alarms also utilize antennas. Some radio antennas were imbedded in the windshield
For American made ham antennas, www.antennas.us has several models of antennas for sale. Their website offers a search bar to find the newest or the cheapest available.
