How this exact system works
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.
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
Survey the support and fall line, lay out and inspect the full radiator, strain-relieve the feed system, raise it without excessive tension, route the coax away from foot traffic, then verify the installed antenna before transmitting.
