CB radio microphone with XLR connector

The Astatic 302-636LB1 is a black noise-cancelling microphone built for CB, amateur radio and SSB communications. It uses a low-impedance dynamic element designed for close-talking handheld use. A polyurethane-coated steel grille protects the capsule. The coiled cord ends in a 4-pin XLR plug.

Upgrade from stock or worn CB handsets

This model replaces original microphones that lack noise cancellation or have damaged cords and connectors. The jump is worthwhile when background noise makes transmissions hard to understand or when the existing microphone element has lost sensitivity. The rugged housing and coiled cord withstand daily mobile use.

Fits 4-pin CB and amateur radio rigs

The XLR connector mates directly with compatible radios that accept a 4-pin wiring scheme. No external power supply or preamp is required because the dynamic element is self-powered. The coiled cord extends for comfortable reach and retracts to keep the operating area tidy. Buyers needing a different pin count or a wireless link should look elsewhere.

Questions about this item

What connector does the Astatic 302-636LB1 use to plug into a CB radio?

The microphone terminates in a 4-pin XLR connector that matches standard CB and amateur radio pinouts.

How is the coiled cord attached, and what step avoids damage?

The cord is permanently wired to the microphone body; route the coil so it cannot snag on the radio chassis when you set the mic down.

When should the polyurethane coated steel grille screen be replaced?

Replace the grille if the coating flakes or the mesh dents enough to let moisture reach the low impedance dynamic element inside.
