How this exact system works
At 3.4 ounces, CHA LEFS FEATHER is the deliberate QRP choice for an operator who counts every ounce but still wants a full-size end-fed wire for 40, 20, 15, and 10 meters without a tuner.
The boundary that prevents mistakes
The system combines a 49:1 End Transformer Unit, BNC female feed, 61½-foot high-visibility 26-gauge PTFE braided-Kevlar wire, integral line winder/end insulator, S-Biner strain relief, and a field-tuning stub. Paracord and coax remain station equipment. Published power is 25 W SSB and 10 W CW or digital. The guide lists 40, 20, 15, and 10 meters without a tuner; 30, 17, 12, and the upper 10-meter FM segment require a tuner. This guide documents a sloper, not a generic horizontal/NVIS configuration.
