The Beat-Sonic FDX9 is a functional shark fin antenna that replaces your factory rear roof antenna with a lower-profile, sportier design - without sacrificing AM, FM, HD Radio, or Satellite Radio reception. Lower profile than other Beat-Sonic antenna models and tested to improve driving stability at higher speeds. Patented design, made in Japan, installs in minutes with no permanent modifications.
Note: only the unpainted model (FDA9N) is currently available. For a color-matched finish we recommend having the unpainted model painted at a local body shop.

Frequently asked questions
Will this work with my Satellite Radio subscription?
The FDX9 is compatible with Satellite Radio signals from OEM - meaning it supports the factory satellite radio antenna signal. It does not add satellite radio capability to vehicles that did not come with it from the factory.
Is a painted version available?
Only the unpainted model (FDA9N) is currently available. For a color-matched finish we recommend taking the unpainted antenna to a local body shop for paint matching to your vehicle's factory color.
Will this fit my roof?
The FDX9 is designed to fit flat to slightly angled roof surfaces. If your vehicle has a highly curved roof, email info@beatsonicusa.com with your year, make, and model to confirm the correct model before purchasing.
How is the FDX9 different from the FDX3 and FDX4?
The FDX9 has a lower profile height at 2.60 inches versus 2.75 inches on the FDX3 and 2.87 inches on the FDX4, giving it the most aggressive, lowest-profile look of the Beat-Sonic shark fin lineup.
Is it safe to go through a car wash?
Yes. The FDX9 is car wash safe.
Does this ship to Canada or internationally?
Yes. We ship to Canada and Mexico.
