This 20-amp noise filter reduces the electrical noise that makes listening to incoming CB transmissions difficult. The filter easily installs using a 3-pin power cord, which plugs directly into the back of most medium to large CB radios. If your radio does not accept a 3-pin plug, you can easily cut the attachment off and match the positive and negative wires.

Product Details:
  • Reduces electrical noise in incoming CB transmissions
  • 3-pin power adapter makes installation easy
  • Filter can be mounted out of sight under the dash or seat
  • Includes inline fuse
Compatible with:
All CB radios. If your CB has a 3-pin plug in back, the noise filer will plug in easily. If not, you can cut the attachment off and simply match the positive and negative wires.

Noise filter

Easy to install, wired radio directly to the battery and has reduced the engine noise a great deal ( not completely ) much better than without.

Installed and working

Good fast service from RCB however the project was put on hold here for a few weeks due to other priorities. It is now installed and working. The only feedback I have is that the screws that came with it were too short as they barely protruded from the body of the device. Not really a problem as I have plenty of screws.

Have not opened the box.

Have not opened the box. Looks like I don't need it after all.

Works okay

While this did reduce the noise, it did not eliminate it. Overall does what it's intended to do.
