CB electrical noise from antenna
My CB use to pick up a ton of engine noise. That would increase with RPM and would have constant interference. I finally fixed that last weekend by running the power straight to the battery with RG8 coax. Now while driving I only pick up other interference from things outside my truck (for the most part I think).
I figured out that it was exterior interference when i pulled up to a light, with know interference. The pedestrian light was on walk and my radio was fine. As soon as the hand started flashing my CB would have loud static every time the hand would flash. Then when it stayed my radio kept the noise. Until i pulled through the intersection. Sometimes my radio will have hardly any static at all, and then it will have full static for few seconds.
Is there anything I can do to help reduce noise from my antenna? I believe I have it grounded fairly well. Its mounted to my toolbox, but the ground wire from the antenna I have running down in between cab and bed, inside the rocker panel, and up into the engine compartment to a grounding point. And i used some solid core wire. Is there anything else i can do besides better ground?
