Cb antenna

Drivers side..Trees n such will take the ant out..Yes on the nylon washer..Already told you..

 

He said neither antenna had a nylon washer:

Quote: "No washer on the antenna the other antenna didnt have washer either, don't have a SWR meter. I'll install a plastic washer and see what happens."

 

Buy a SWR meter, cheap tool that will pay for itself many times over and eliminate guessing.

 

Nylon washer between ant stud and mount"HAS" to be there to work..Otherwise your ground out the ant which will mess up the radio after awhile..
On some ant there is a rubber o ring but thats just to keep it snug and water tight..

 

Shouldnt be a little..Should not work w/o washer between mount and top part of ant stud..
Google a pic of ant stud to see..

 

Clean your grounds, you now have a grounding issue, cant tell exactly what you need without seeing it, sugest take the mirror apart and clean up the install.

 

Tuning the radio is not gonna fix that..Just unhook the cb coax and unwind the tarp..If the noise is there still you likely will need to run the radio direct to battery,its a possible fix...If its not then its antenna related..
