CHA LEFS FEATHER EFHW

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.
