Default Light bar interferes with CB radio?

I have a 50Ē curved light bar wired to an on/off switch. I recently installed a CB radio that works fine until you turn on the light bar. As soon as I turn on the light bar, thereís an awful, loud, patchy static noise that comes through the radio. I think the light bar must be interfering with the antenna somehow. Itís kind of annoying because I canít use them both at the same time. Iíve recently noticed it actually interferes with the OEM stereo in the same way when Iím listening to an FM station. I donít really know how to go about fixing this, if I even can. Could someone help me out? Thanks.

I would assume you don't have a strong ground for the lightbar or it's possible that the light bar is throwing out some EMI.

Is your CB antenna wire isolated from any power wires (if you run a power wire next to the CB Antenna wire, you will get interference)

The only power wires the antenna is close to is the power to the CB itself.

I was actually considering using some ferrite chokes, like the ones on laptop charger cords. Theyíre supposed to suppress electromagnetic noise I guess
