Extend the reach of your CB microphone cord by an additional 15 feet. This custom built cable provided by Walcott Radio has a male connector that fits into any standard 4-pin CB microphone, the other connector is a standard 4-pin female connector that plugs into your radio. A great solution to extend the reach of your microphone, especially if your radio is located somewhere inconvenient, or if you don't want a microphone cable dangling in front of your face. Simply plug in the cable into your radio, route the 15 foot extension wherever is convenient, then plug in your microphone there.
