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
Check site rules and weather, select the first band before raising the antenna, protect the public footprint, verify at low power, log the geometry, then recover and inspect every component before leaving.
