Antenna mounting bracket

Once You have CB radio in the car, you need attach antenna. I used the Albrecht 6725 Gamma II F CB, maybe you have other one. There is no need to drill in the body, there are holes and scrtews which can be used. Of course, inside the bracket there is a solid iron core 90x40x40 mm. 

The strength of this mount is ensured by a 3D-printed plastic holder that prevents the antenna from shaking.
