The antenna stays in place for motorcycle ETC car devices where the antenna is separated from the main unit.
There are 2 types of shapes, L and V shapes, and each color is black and silver.
Please use double-sided tape to secure the antenna.
If you fasten the stays to your vehicle, you can also use double-sided tape as well as fixing the antenna, but you can drill a hole and secure it with a bolt.
The material is aluminum, so you can easily cut and drill holes.
