A-302 cables are a group of coaxial cables designed for automotive applications, they include specific manufacturer variations like DACAR 302, TFC-302, and RTK-031. These cables share a common 3.2 mm outer diameter, 2.1 mm dielectric diameter, and stranded centre conductor. Most manufacturers specify performance up to about 3 GHz.
