Radioddity HF-010A Antenna Adapter | PL-259 to 3/8-24 | Compatible with HF-010/HF-009

The Radioddity HF-010A is a heavy-duty PL-259 to 3/8"-24 antenna adapter, engineered for HF mobile, POTA, SOTA, and vehicle-mounted operations. It provides a secure, stable interface between SO-239 mounts and standard 3/8-24 threaded HF whips or loading coils, ensuring reliable performance in the field. Its robust, high-mass construction (approx. 0.35 kg) minimizes signal loss while enhancing mechanical durability and vibration resistance—ideal for long-term mobile use and rough terrain deployment. Features PRECISION THREAD ADAPTER: Converts standard PL-259 (UHF Male) to 3/8"-24 male threads. Designed for quick, secure installation of HF whips and loading coils, facilitating accurate SWR tuning for mobile installations. STABLE HF SIGNAL LINK: Supports 3-50MHz with SWR ≤1.5:1, providing a low-loss bridge between SO-239 mounts and 3/8"-24 antennas. Ideal for clear 80m-6m band communication during POTA activations and field days. 150W HIGH POWER RATING: Designed to handle up to 150W without signal loss, the HF-010A provides reliable, precise SWR tuning for vehicle-mounted and portable HF antennas, ensuring optimal performance and protecting your radio from high-reflection damage. RUGGED CONSTRUCTION: Crafted from a solid 304 stainless steel exterior for unmatched durability and corrosion resistance, protecting the precision threads even in harsh environments. Inside, a pure copper core ensures maximum conductivity and minimal signal loss. Weighing in at a substantial 0.35kg (0.77 lbs), this heavy-duty adapter dampens vibration, keeping your antenna secure and resonant—whether you're on a windy balcony or navigating rough off-road terrain. BROAD COMPATIBILITY: Fully compatible with Radioddity HF-010/HF-009 antennas, M916 magnetic mounts, and most standard 3/8-24 threaded HF antennas, providing a secure, reliable connection for a wide range of mobile and portable HF setups. 　 Specifications： Frequency Range: 3.5MHz - 50MHz Connector Type: PL-259 (UHF Male) to 3/8"-24 Male Material: 304 Stainless Steel (Body) + Pure Copper (Core) Max Power: 150W (SSB) Impedance: 50 Ohms SWR: ≤1.5:1 Weight: 0.35kg (0.77 lbs) What’s in the box? 1 x HF-010A Antenna Adapter
