If you drive a BMW Z3, you probably love cruising. And what makes the ride? The enjoyable handling of a roadster, the agility of a coupe, and the top-down freedom of a convertible, sure. But also: what else but great tunes through a car radio with a good antenna? In the old days, antennas used to be AM/FM only, but these days, you can get clearer digital reception from a satellite or ground repeater via an antenna with a receiver module. Plus, there are many HD sources out there, provided you have the right tuner or receiver. You have many different antenna types to choose from. External antennas, you may know best. They're usually made of metal or fiberglass and typically installed near your hood or trunk. They get better reception, but they're exposed to the elements. Internal antennas, you can often find inside your trunk or dashboard or on your windshield, and they're usually safer from accidental damage, let alone weather. However, they sometimes need a built-in amplifier to get the best signal. Whip antennas are usually external. Most of the time, they're straight fiberglass rods with wire cores designed flexible for durability, and their bottom ends connect to a radio receiver or transmitter. Retractable antennas are also often external, and there are two subtypes: manual and automatic. Manual retractable antennas, you can push down to conceal. Automatic retractable antennas are usually powered by reel motors; you can pull them back with the touch of a button. If you're looking to replace a broken antenna or upgrade your car entertainment system, the best antenna for your BMW Z3 is genuine. After all, one made by your OEM is made to fit its sports cars specifically. You can order one direct from BMW, right here at our auto parts store. Buy now -- and don't forget the cables and masts!
