Ive got so much engine noise coming thru my radios, I was thinking about installing a battery in the rear of my vehicles and running direct to the cb. When the battery would run down a bit, I would just charge it back up. Any responses would be greatly appreciated.

When the battery would run down a bit, I would just charge it back up. Any responses would be greatly appreciated. Depending on where the noise is coming in from, running a separate battery may not solve the problem. If the noise is conducted through the power leads, you might be able to knock it down, but if it is being picked up by the antenna, then it will not help you. The way to determine whether the effort of running a separate battery is worth your time is to start the engine. Make note of the noise, then unplug the antenna lead. If the noise goes completely away, then your issue is noise being picked up by the antenna, and the separate battery won't help you. If the noise stays when the antenna lead is unplugged, then running the separate battery might help. In lieu of the separate battery, you might try in-line noise filters. They sell them at mobile stereo shops and places like Radio Shack at one time carried them as well. |

Put SEVERAL "GOOD" ground straps from the frame of the vehicle to the body.Also lots of mobile noise comes from the exhaust system which should also be grounded VERY well to the frame at least in TWO different spots(front & rear).Ad a couple of snap on FERITE beads onto the power & ground leads as well as the coax cable.On the grounds make sure that you are attaching to BARE metal(grind or wire brush the area) & NOT something covered with undercoating or your wasting your time.Hope this helps.
