Steel CB whip @ 60mph

hello Tacoma world, I have a 108" steel CB antenna. Works great when I'm not moving. It's mounted on the right front bumper with a spring....when I'm going at highway speeds its bends like no other and shakes vigorously. When I PTT I get antenna warning. I really want my CB to work on the highway not just on the trails. What do I do?

 

Mount it in back and run a string/fishing line to the top from the front end of the bed.

 

I really wanna keep it in the front

 

Replace that steel antenna with a 4-foot K40 or Firestick.

Otherwise, just live with it.

 

Found the problem. it was a bad ground to my antenna!

 

You need some kind of non metallic bracket between the antenna and body, like the top of the core support, to keep the antenna at a stable distance from the body. As the antenna gets closer to, or farther away from the body the swr setting will change drastically.
