How this exact system works
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. Treat the product as a complete documented system: feed point, radiator, return or balanced second leg, feed line, support, geometry, power, and environment all matter.
The boundary that prevents mistakes
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.
Use this field sequence
Raise the far-end line winder about 20–25 feet, keep the transformer around three feet above ground, allow some sag, and use the S-Biner and isolation ring for strain relief. The guide specifically recommends 15- or 25-foot RG-316 with its integrated choke and identifies CFM-16 as the tree-free lightweight support partner.
