Core selling points: Efficient impedance matching (1:4 conversion ratio): Accurately convert input 50 ohms (unbalanced) to output 200 ohms (balanced), greatly improving signal transmission efficiency, reducing energy loss, and ensuring clear communication without interference. Wide frequency band coverage (1-56MHz): Supports shortwave full-band applications, seamlessly switching from low frequency 1MHz to high frequency 56MHz, suitable for multi-scenario communication needs, such as amateur radio, ship communication or field operations. High power tolerance (500W power tolerance): Adopting industrial-grade materials and heat dissipation design, it can stably handle 500W high-power loads, avoid overheating damage, and equipment safety and . Professional Winton antenna structure: Based on the classic Winton antenna design, it enhances balance and anti-interference capabilities to reliable operation in harsh environments (such as high humidity or multi-interference areas). Transformation ratio: 1:4 Input impedance: 50 ohms (unbalanced) Output impedance: 200 ohms (balanced) Frequency range: 1-56MHz VSWR: less than 1.5 Power handling: 500W (continuous operation) Dimensions: OD 57mm x Length 175mm Weight: 350g Operating temperature: -20C to +70C (standard industrial range) Application scenario suggestions: Amateur radio enthusiasts: Improve HF band signal quality. Emergency communication team: reliable connection at disaster sites. Ship or aviation communication: Strong anti-interference ability and adaptability to changing environments. Education and scientific research: Used for antenna experiments and teaching.
