Astatic 302-10187 4-Pin Noise-Cancelling CB Microphone, Chrome

The handheld Astatic 302-10187 is a 4-pin noise-cancelling microphone for close-talking radio communication. Its format makes it easy to hold while speaking, whether you’re in a truck or using a compatible CB, amateur-radio or SSB setup.

A low-impedance dynamic element and unidirectional pickup pattern are designed for focused voice use. Noise cancellation is a useful feature in settings where background sound can compete with speech.

The chrome-plated housing, polyurethane-coated steel grille and flexible stainless steel cord give the microphone a rugged construction for regular handheld use. It is a communications-focused choice rather than a general-purpose microphone for studio recording.

What to know

The 302-10187 combines a 4-pin connection with a low-impedance, 600-ohm dynamic element. Its stated frequency range is 30 Hz to 20 kHz, and the microphone has a single channel. The product is listed with a 12-volt power source, so match it to a compatible radio setup before use. It is designed for close-talking applications with CB, amateur radio and SSB communications, including truck environments where background noise may be a concern.

The physical design supports everyday handling: a chrome-plated housing surrounds a polyurethane-coated steel grille, while the flexible stainless steel cord connects the mic to the radio. Customers often describe the sound as clear and loud and say the microphone works well. Feedback is more divided on cord length and how much background noise is reduced, so experiences can vary by setup and surroundings.

Tips for day-to-day use

For the intended close-talking style, speak near the microphone rather than holding it at a distance. This keeps the mic in the use position it was designed for and helps make voice communication practical in a busy cab or other noisy setting. Connect it to a compatible 4-pin radio system, and ensure the setup matches its stated 12-volt power source.

The microphone’s handheld form is suited to speaking and setting it down between transmissions. Its steel grille and rugged housing are practical construction details for a mic that is regularly picked up and used. Keep the cord positioned so it can move freely while you handle the microphone, buyers have differing preferences about its length.

Getting the most from it

This model makes sense when the priority is a handheld microphone built specifically for radio communication, rather than a mic selected for broad recording or studio use. Its 4-pin connection, low-impedance dynamic element and close-talking design give it a clear purpose for compatible CB, amateur-radio and SSB systems. The unidirectional pattern and noise-cancelling design are relevant in settings such as truck cabins, where background sound is part of the working environment.

A practical setup is a compatible radio with the microphone within comfortable reach: pick it up to speak, hold it close, then set it down when finished. The chrome finish and polyurethane-coated steel grille provide a distinct, durable-feeling exterior, while the flexible stainless steel cord supports movement during handheld use. Customer comments also point to clear, audible sound, alongside mixed views on the cord and noise cancellation.

Is it worth it?

Worth considering if you need a purpose-built 4-pin microphone for compatible CB, amateur-radio or SSB communication. Its close-talk handheld format, low-impedance dynamic element and noise-cancelling design suit voice use in settings such as trucks, while the rugged housing and steel grille support regular handling. For radio users looking for a dedicated communications mic rather than a general recording microphone, the Astatic 302-10187 brings together the connection and design features that matter for that job.
