Description
The CHELEGANCE JEFHW-4010-150 is a high-performance 4-band End-Fed Half Wave (EFHW) antenna designed for HF amateur radio operators who need a simple, reliable, and portable solution. Covering the 40m, 20m, 15m, and 10m bands without requiring an external tuner, it delivers efficient operation in a compact, single-support setup—ideal for portable activations, base stations, and emergency communications.
Engineered for natural resonance on 40m, 20m, 15m, and 10m, delivering low SWR (typically ≤1.5:1) without the need for an external tuner. Just connect and operate.
Built with a precision-wound 49:1 (or 64:1) Unun using high-quality ferrite core, ensuring low loss and stable performance up to 150W PEP.
Unlike dipoles, this EFHW requires only one elevated support point, making setup faster and more flexible in portable or limited-space environments.
Lightweight wire structure and compact matching box make it ideal for POTA, SOTA, field day, and emergency communications.
Supports horizontal, sloper, and inverted-V configurations, allowing you to adapt to different terrains and operating conditions.
