Interference may be caused by non - resistor spark plugs. If you don't want to change your plugs for resistor plugs, you may be able to get an inline resistor for the antennae from your local electronics supply store, like radio shack.

If you buy the new antennae, go to a cb shop to have your antennae tuned to your cb - it will increase your range and clean up your sound too.
