The MK393 replacement CB Microphone for Uniden PRO510XL and PRO520XL CB radios is genuine Uniden mic.

If you've owned and used a CB radio long enough you know that there will come a day when the OEM handheld microphone will need to be replaced. Perhaps it's been dropped once too many times, or the wiring in the coil cord has failed. Now you can get the same excellent, compact, lightweight microphone that your Uniden radio shipped with in a factory replacement.

The MK393 is a sturdy microphone with cable strain relief at both ends. Cable strain relief helps to prevent cable separation from the mic's connectors due to overstretch of the mic cable syndrome. The Uniden MK393 CB microphone is a 4 pin electret model that is a lightweight microphone with excellent modulation.


The MK393 microphone is a 4 pin electret CB microphone. It is compatible with smaller CB radios that use an electret mic. Larger radios will have reduced (sometimes inaudible) audio with this microphone. This is the factory replacement for PRO510XL and PRO520XL CB radios from Uniden.
