The Jetfon DB-25SM is a professional-grade, extended dual-band portable antenna engineered to maximize signal range and reception sensitivity on handheld transceivers and wideband radio scanners. Measuring 36.5 cm in length while maintaining an ultra-lightweight mass of just 9 grams, this high-performance whip antenna delivers an exceptional blend of mechanical flexibility and electrical efficiency. It is an ideal hardware upgrade for security coordinators, field technicians, and radio communications professionals who require superior range capabilities without adding structural strain to their equipment.
Engineered with an advanced 1/4-wave radiator architecture (optimized at 145 MHz), the DB-25SM provides optimal impedance matching and excellent resonant efficiency for stable voice transmission across standard VHF (2-meter) and UHF (70-centimeter) bands, supporting up to 10 Watts of maximum RF power. Beyond dual-band transmission, its internal conductor matrix is precision-tuned for full-band coverage in reception (Full Band RX), making it a top-tier choice for monitoring extended frequency spectrums on multi-band receivers. Featuring a standard SMA Male connection interface, this antenna guarantees a solid mechanical lock and low-loss signal continuity on a wide variety of multi-brand professional transceivers.
