The genuine antenna was broken before I knew it, so I replaced it.
Designed exclusively for the NC / ND Roadster, the size of the mounting part is perfect!
When I listen to AM radio, it seems that there is a little noise depending on the driving area, and it is not as clear as Mazda genuine.
However, I didn't care about FM radio.
