Are you fed up with line interference and electrical noise on your CB, Scanner, stereo, and two-way radio? A CB Radio Noise Filter from Workman Electronic Products, the Bandit CBNF3AXX CB/Stereo power noise filter will reduce engine and electrical noise on your radio.

The Bandit Noise filter is a 20 amp inline filter specifically designed for tackling noise from alternators, engine, wiper motors, and other automotive electronics. The CBNF3AXX power noise filter includes the 3 pin power plug most new CB radios use. The plug can be removed to adapt this device to work with many other radios.

Carefully following the included installation instructions for the Bandit power noise filter will protect your automotive electrical system, radio, and reduce line noise.

Unfortunately, if the noise is emanating for your antenna the Bandit noise filter will not be of help.

Dear Twister2014,

We have not heard of this before. It might be where you are pulling your power from or ground. Maybe try running the ground to the chassis or to the battery and try a different source for 12 volts.

Hope that helps!
I have a 2005 chevy silverado and it doesn't matter if you use a magnet antenna or a mount antenna it kills the oil pressure gauge in my instrument cluster any help with this issue would be greatly appreciated
This Filter is a Really Nice Design especially since it has the "Radio" Power Cord Built-in which made it a Very Easy Install. I was getting Noise from the Engine and Stereo in my Truck. The Stereo is Aftermarket and 1100 watts of it is a Problem when I'm using Both the Stereo and the CB Radio. After I installed this Filter 98% of the Noise Problem has Stopped.
It did take care of ALL the Engine Noise and Most of the Stereo Noise. When Compared to the other Two Types and Brands I've Installed, this Model is the BEST of the Bunch! The others never helped at all with the Stereo Noise Problem, so this Filter did the Job, it worked Great!
I'm Very Satisfied with the Results and I would Definitely Recommend this Product to anyone who is having issues with Noise.
Thank. You. For. This. Gadget. I've been putting up with this buzzing/popping noise on my radio since I installed it. I finally got fed up and called CB World. I plugged this in the line in place of the stock power cord and, BAM!, no more problems!
