CHA LEFS FEATHER Horizontal and NVIS Guide

The current CHA LEFS FEATHER guide documents its portable sloper; it does not authorize a horizontal/NVIS geometry.

Start with the operator’s decision: The current CHA LEFS FEATHER guide documents its portable sloper; it does not authorize a horizontal/NVIS geometry.

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

Use the documented sloper. If regional/NVIS coverage is required, select a Chameleon system whose current guide explicitly controls a horizontal or other NVIS-oriented configuration.
