Radio static is caused by one of two things: a suppressor or the antenna.
If you notice static during certain moments, like when you change speed in your car, then it’s a suppression issue.

It could be an alternator or ignition system issue, both of which require more technical knowledge to fix.
If you notice static consistently, this indicates a problem with your antenna, which is much easier to fix. You can try tightening the antenna back into its base (it loosens over time). There might also be corrosion at the base, in which case you can clean the base or get a new antenna.
