Greetings,
I've got an antenna mounted via an ¬ mount to the side of my trucks aluminum toolbox. I've also got a portable BC246T scanner, the handheld variety.
I plug my scanner BNC into the antenna mounted on the toolbox. I then connect the earphone plug using a MALE-MALE cable to the INPUT jack on my stereo headunit. This is done to get sound via my car speakers.
When I start my vehicle, I hear a sort of noise. When I rev the engine, the noise increases. When I flip my blinker, the noise oscillates when the blinker draws current.
If I disconnect the antenna and apply the rubber ducky, there is no noise.
Is this noise that is being radiated via the metal body of the vehicle into the antenna, through the antenna ground to the mobile ground, and up into the radio from the scanner?
Any ideas on this? Ways to eliminate?
