I'm new to cb's, I've had this one for a couple of months. It's a Cobra 29LTD Classic. I have it on a magnetic firestik like antenna. All new. It's in my Cat 525d Skidder. I can't reach out more than 500 yards. That's it. Someone says it's the tractor cause the cab sits on rubber bushings to dampen the noise, causing it to not ground out good. I don't know, but help, please.
Having trouble getting out.

Do you have the excess coax coiled together? Mic gain turned up?

What does you SWR look like.

3. On 1 and 40

You have an issue with common mode current.
Common mode current
uncoil the coax, put it in a figure eight if you need to take some up. see what happens and if it improves, then get the antenna tuned to see if that helps - 3:1 is high.
If you still have issues, then you may have to put a choke on the coax to take out the current on the outside part of the coax. -
I think you need to get rid of the mag mount and get a different mount that you can ground to the frame. Your chassis is sitting on rubber bushings . So you antenna system isn't properly grounded.
Don't operate your radio with your swr being that high.
