Does it go away when you shut off the engine? Yes
Does it go away when you Disconnect the antenna? Haven't unhooked just the antenna from the mount.
I don't have a pic but can take one. It's inside the license plate housing so I'll have to pull it. The Ultamount came preassembled so I assumed it was correct. I'll post pics tomorrow.

and we need you to Disconnect the antenna while you are hearing the noise to see if it goes away to see if it's the antenna ground or the radio power.

When I get home I will pull the antenna and give an update. I'll also look to see what side the washer is on the mount.
Could all the engine noise be helped if I upgraded the wiring to a thicker gauge wire possibly? The stuff on the CB isn't that substantial.

Not sure what my next step is here.

It's not in your cb or the wiring it's in your antenna system. You mentioned running an aux ground off that antenna mount is that true? If so where does that ground go?

With a mobile setup, your whole system kind of works together. If you are confident you got a good ground with the power wire, that's not the problem... as stated above.
Bigger supply wire shouldn't help you with noise. You need about 12g though, 14 would do I suppose. It's probably not that.
How is that bracket attached to your vehicle? If it's mounted to metal, you don't need a grounding strap. Either way you are making contact with your frame, make sure paint is chipped away so you are getting a good connection. Grounding straps can do funny things to antenna systems. How are you attaching the strap to the frame? I couldn't see it in the picture.
Please don't buy a filter. It sounds like a grounding problem. Fix the actual problem, don't just try to cover it up.
