The Jetfon DMC-502/4 is a commercial-grade professional handheld transceiver microphone engineered to deliver high-clarity voice transmission and dependable long-term duty performance for CB-27 (Citizen Band) mobile communication setups. Housed in an ergonomic, high-impact black polymer casing, this dynamic communication mic features an optimized circular front acoustic grille with integrated horizontal slots and the official screen-printed Jetfon layout insignia. Outfitted with a tactical non-slip lateral Push-To-Talk (PTT) switch, it provides low-latency, precise single-handed transmission control for mobile operators, transport fleets, and commercial distribution networks.
Built to withstand heavy multi-shift workplace environments, the DMC-502/4 incorporates a high-elasticity black curly coiled cord configuration designed with a heavy-duty strain-relief sleeve assembly at the housing exit to prevent operational wire fatigue. This specific hardware variant comes pre-terminated with a premium 4-pin interface connector (Reference: 0412), engineered to ensure a tight mechanical coupling and low-attenuation electrical connection with compatible citizen band radio frames. The system delivers a balanced 500-Ohm nominal impedance profile that optimizes audio response while limiting background sound distortion in active driving conditions.
