Radioddity HF-010A HF Antenna Adapter, PL-259 to 3/8-24 Mobile Ham Radio Connector for POTA SOTA Field Use, 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. Operating across 3–50 MHz with 50-ohm impedance, the HF-010A supports up to 150W, maintaining a low SWR (≤1.5:1) when properly tuned. 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.

• PRECISION THREAD ADAPTER: Converts standard PL-259 (UHF Male) to 3/8"-24 female 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: Features a high-mass 0.35kg solid build for superior vibration resistance. This heavy-duty adapter ensures your antenna stays secure and resonant even when operating on 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.
