Finishing up the body work on convertible RX7 and welded up the power antenna hole to make the car a little sleeker.

NEW cars don't have radio antenna masts. What aftermarket options are out there that don't look cheap and shitty for a radio antenna?

 

You can get small antenna 'boxes' that mount up on the top of the windshield. Either that or a small 'fin style' antenna will work. You should be able to find both easily on eBay, just make sure to get the correct adapter depending on your radio/headunit output.

 

Is it possible to do a hidden antenna, and shave the exterior one? I'm a fan of the built-in-pillar antenna of many new cars.
