Power inverter noise

Inline noise filter direct from battery to your CB, and a direct ground. Will also remove the alternator noise you hear. You could just toss in a quick inline but it wouldnt be as effective

 

Any CB shop can install a noise filter, or you can pick one up yourself for 25$ and run it yourself. I prefer direct connection, but you can also run off the standard truck wiring but you still have to hook the filter direct to batt if you want it to clean it up fully.

 

This is the solution to your problem but it costs ten times as much as your inverter.

 

That's what most people choose to do. I like to take the expensive route

 

Go to a outdoor shop like an rv world..Talk to them about inverters..Truck stop ones and most auto shops n such sell cheaply made inverters..Rv shops usually sell them that dont cause whats called dirty power..
