Antenna Cable Issue

Radio might show an antenna warning when there are faults or scratches in the antenna cable. Sometimes antenna cable or socket becomes rusty if the cable gets wet and shows a warning On the CB screen. So, check the CB antenna cable from beginning to end to find out what exactly happened in the antenna.

  • If your first two steps fail, this will surely work to remove the antenna warning though the process is slightly complex. Turn off the radio and remove all the cables behind it and take it into your hand. Take a screwdriver from your vehicle toolbox and remove all the small bolts from the CB radio.
  • After removing the bolts, the radio cap will be open automatically, and then remove the cover with caution. There is a circuit board with a lot of electrical components in the CB radio. Don’t make the process complex with unnecessary cables touch in the CB radio.
  • Besides the power cable, you will see a black-colored electrical component named VR6 in the circuit board, and the whole purpose of opening the CB radio is VR6. Now turn on the radio but don’t connect the antenna, and still, you will see the warning.
  • Then keep the screwdriver on the VR6 like putting the screwdriver on the bolts. Then, turn the VR6 clockwise but not too fast and keep your eyes on the screen. Turn it slowly until the warning removes from the screen and if it disappears, stop turning.
