LEFS FEATHER EFHW · Wire Antennas A wire radiator or wire antenna system for documented horizontal, sloping, inverted-V, inverted-L, dipole, or NVIS use. Why operators make room for it Put useful wire in the air without carrying a permanent tower A field site may offer height, distance, or concealment—but rarely all three in exactly the right places. That is where CHA LEFS FEATHER EFHW enters the kit. The CHA LEFS FEATHER (Lightweight End Fed Sloper) is a purpose-built portable HF antenna designed for operators who demand maximum performance with minimum weight. That flexibility gives an operator a credible path from a compact field kit to a full-size radiator, while the official configuration still governs feedpoint, support, tuning, and safety choices.

Limitations Never mount this, or any other antenna near power lines or utility wires! Never trust insulation to protect you. Never operate this antenna where people could be subjected to high levels of RF exposure, especially above 10 watts or above 14 MHz. Never use this antenna near RF sensitive medical devices, such as pacemakers.

Open documentOpen product handbook What an operator can do Select a documented horizontal, sloping, inverted-V, inverted-L, dipole, or NVIS arrangement. Raise the wire with a support that satisfies the antenna guide's height, load, insulation, and guying limits. Keep balanced dipole configurations symmetrical and do not add radial or counterpoise accessories unless the guide explicitly requires them. Balanced-system rule: Do not add radial or counterpoise accessories to a dipole configuration unless the official guide explicitly requires them. Complete product details Introducing the CHA LEFS FEATHER – Ultra-Light HF Performance, Reinvented The CHA LEFS FEATHER (Lightweight End Fed Sloper) is a purpose-built portable HF antenna designed for operators who demand maximum performance with minimum weight. Weighing only 3.4 oz (96 grams), this antenna is engineered for POTA, SOTA, backpacking, emergency communications, and rapid deployment where portability and reliability are critical. What Makes the LEFS FEATHER Different At the core of this antenna is what truly separates it from everything else in its class: the wire. The LEFS Feather uses a custom high-quality 26 AWG PTFE Military Kevlar wire, not standard stranded copper. This reinforced composite conductor features: A 26 gauge copper radiator An interwoven Kevlar core A PTFE (Teflon) outer jacket Advantages of the 26 AWG PTFE Kevlar Wire This wire is engineered for real-world use and delivers performance and durability that standard antenna wire cannot match: It does not kink, eliminating memory and permanent bends during deployment and recovery The Kevlar core carries the mechanical load, protecting the copper from stretching and fatigue Extremely lightweight while maintaining high tensile strength PTFE insulation provides superior resistance to heat, abrasion, and harsh environments Reduced long-term failure compared to standard stranded copper High-visibility orange for faster deployment and easier recovery This is a military-grade wire solution, built for operators who rely on their equipment. Multi-Band Performance The CHA LEFS Feather is a true End Fed Half Wave antenna that provides: Operation without a tuner on: 40M 20M 15M 10M Operation with a tuner on: 30M 17M 12M Built for Real-World Deployment High-performance 49:1 transformer with no compensation coil required Efficient sloper configuration for optimal field performance Single-operator setup in under 10 minutes Compact and highly portable for rapid deployment anywhere What’s Included Each CHA LEFS FEATHER package includes: End Transformer PCB Unit with integrated 49:1 matching transformer and BNC connector Approximately ORANGE 66.5 ft of 26 AWG PTFE Kevlar-reinforced antenna wire Integrated End Insulator and Line Winder system S-Carabiner clip for quick attachment Everything is designed as a complete, ready-to-deploy system. Specifications Frequency (no tuner): 7.0 – 7.3 MHz (40M) 14.0 – 14.35 MHz (20M) 21.0 – 21.45 MHz (15M) 28.0 – 28.5 MHz (10M) Frequency (with tuner): 10.1 – 10.15 MHz (30M) 18.068 – 18.268 MHz (17M) 24.89 – 24.99 MHz (12M) 28.5 – 29.7 MHz (10M FM segment) Power Rating: 25W SSB 10W CW / Digital RF Connection: BNC Female SWR: Less than 2.0:1 across supported bands (depending on environment and setup) Length: Approximately 61.5 ft Weight: 3.4 oz (96 grams) Wire Type: 26 AWG PTFE Military Kevlar reinforced wire Setup Time: One operator, less than 10 minutes Designed for Operators Who Move Whether you are activating a summit, operating in a national park, preparing for emergency communications, or working within HOA restrictions, the LEFS Feather provides a full-size HF solution in an ultra-compact form factor. The Bottom Line The CHA LEFS FEATHER delivers: Advanced wire technology Reliable multi-band HF performance Fast and simple deployment True portability without compromise This is not just a lightweight antenna. It is a serious HF tool built for real-world operators. Versatile. Dependable. Stealth. Built to Last.
