A Beat-Sonic antenna is the difference between a shark fin that works and a shark fin that just sits there. Every antenna in this collection is a true functional replacement for your factory mast, with a real helical coil element inside that keeps AM, FM, HD Radio, and Satellite Radio reception intact. Most come pre-painted in high-quality OEM colors so they look factory-installed. Made in Japan, installed in minutes, and fully reversible.
Functional Antennas, Not Cosmetic Covers
Here is the problem with most shark fin antennas sold online: they are cosmetic. A shark fin antenna cover either glues over your existing mast or replaces it and kills your radio reception entirely. Beat-Sonic builds the antenna itself. The helical coil inside the fin connects directly to your factory antenna base with an included M4, M5, or M6 screw, so the fin is not hiding your antenna, it is your antenna. If you want the best shark fin antenna rather than the best-looking paperweight, functional is the only spec that matters.
How a Shark Fin Antenna Replacement Works
Your factory mast screws into a powered antenna base on the roof. To replace a car antenna with a shark fin, you unscrew the mast, thread the Beat-Sonic helical element into the same base, and secure the fin housing with the included 3M double-sided tape. No drilling, no cutting, no wiring changes, and the whole install is reversible. Reception is engineered to match or exceed the factory mast, and the FDX fins are car wash safe.

The universal FDX3, FDX4, and FDX9 fit a wide range of vehicles with screw-on mast bases, with confirmed fits including Toyota, Scion, Subaru, Nissan, Mazda, Honda, Mitsubishi, and Volkswagen models. Pre-painted options use high-quality OEM paint, and unpainted versions are ready for your body shop to match any color. Measure your factory antenna base before ordering, and email info@beatsonicusa.com with your year, make, and model if you are unsure.
Installation in Minutes
No wire cutting, no soldering, no special tools required. Unscrew the factory mast, attach the helical element with the included screw, clean the roof with the included alcohol wipe, and set the fin with its 3M tape. A car antenna swap like this takes minutes, not hours, and removal returns the car to stock. Instructions are posted at our manuals page, with install videos on the Beat-Sonic USA YouTube channel.
