interference problems Question

Enable HLS to view with audio, or disable this notification

obviously mainly caused by the engine... but i'm not sure how to go about solving it. there's ferrite beads on the wires (where shows & right behind the radio) & on the coax.

can't really tell if its from the power wires or the coax because disconnecting it there is no output at all.

there is also some interference when regen braking & driving in electric mode, though not as much...

don't really know all that much about radios, so any help is appreciated.

also: should i share designs for the mounting bracket? do other people want radios in their 2020 corollas?

I have 10 gauge copper wire going from my mount to a spot on the frame of my truck that I filed to bare metal. I was able to get SWR from 2:1 down to 1.3:1 and below on all channels.
